Java is a computer programming language that is concurrent, class-based and object-oriented. It was originally developed by James Gosling at Sun Microsystems. Java applications are compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture.

When you install the download you get the option of choosing where to put the SDK on your hard drive. I am just using the default directory provided by Oracle, which in my case on my Windows 7 system is C:Program FilesJavajdk1.7.025. Where you put the SDK is up to you but remember the path for a bit later in this lesson. Mac: Export JAVAHOME=/Library/Java/Home Next important thing is to add Java compiler location to System Path. Windows: Need to add another string- C:Program FilesJavajdk1.7.025bin to the end of the system variable: Path.

Java is currently owned by the Oracle Corporation which acquired Sun Microsystems in 2010. Following tutorial will show you how to setup and configure Java 1.7 on Windows so you can develop and run Java code.

Download Jdk1.7.0_25

Check following posts if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.8, JDK 1.9 or JDK 1.10.

• Java SE 7 Archive Downloads. Go to the Oracle Java Archive page. Thank you for downloading this release of the Java TM Platform, Standard Edition Development Kit (JDK TM).The JDK is a development environment for building applications, applets, and components using the Java programming language.
• Update Release Notes Index; Java™ SE Development Kit 7, Update 25 (JDK 7u25) The full version string for this update release is 1.7.025-b15 (where 'b' means 'build') except for Windows on.
• . If you do not have Java SE 7 Update 25 installed on your PC, download the installer from the Java SE 7 Downloads page. You need the jdk-7u25-macosx-x64.dmg file. One Allen Center 700 Central Expressway South, Suite 110 Allen, TX 75013.

Java can be obtained from the Oracle Java download page. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows.

In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.

As we are installing an older Java version, you need to scroll all the way down to the bottom of the Oracle Java download page and click on the Download button in the Java Archive section. Then look for the Java SE 7 link and after clicking on it, select the correct operating system under Java SE Development Kit 7u80.

Here is the direct link to download the jdk 1.7.0_80 installer for Windows 32 or 64 bit.

Accept the License Agreement and pick the correct download for your operating system. In this example, we will use the Windows 64 bit version.

Sign in using your Oracle account (or create a new one) and the download should start. Once the download is complete, locate the jdk-7u80-windows-x64.exe file and double-click to run the installer.

Click Next and on the following screen optionally change the installation location by clicking on the Change.. button. In this example the install location was changed to 'C:Javajdk1.7.0_80'. From now on we will refer to this directory as: [java_install_dir].

Next, the installer will present the installation location of the public JRE. We will skip this part of the installer as the JDK installed in the previous step comes with a private JRE that can run developed code. Just press Cancel and confirm by clicking Yes in the popup window.

Click Next and then Close to finish installing Java.

In order for Java applications to be able to run we need to setup a 'JAVA_HOME' environment variable that will point to the Java installation directory. In addition, if we want to run Java commands from a command prompt we need to setup the 'PATH' environment variable to contain the Java bin directory.

When using Windows the above parameters can be configured on the Environment Variables panel. Click on the Windows Start button and enter “env” without quotes as shown below.

Environment variables can be set at account level or at system level. For this example click on Edit environment variables for your account and following panel should appear.

Click on the New button and enter “JAVA_HOME” as variable name and the [java_install_dir] as variable value. In this tutorial the installation directory is 'C:Javajdk1.7.0_80'. Click OK to to save.

Click on the New button and enter “PATH” as variable name and “%JAVA_HOME%bin” as variable value. Click OK to save.

Note that in case a 'PATH' variable is already present you can add “;%JAVA_HOME%bin” at the end of the variable value.

The result should be as shown below. Click OK to close the environment variables panel.

In order to test the above configuration, open a command prompt by clicking on the Windows Start button and typing “cmd” followed by pressing ENTER. A new command prompt should open in which the following command can be entered to verify the installed Java version:

The result should be as shown below.

This concludes the setting up and configuring JDK 1.7 on Windows.

Introduction

How do we know “how it is being done” when we look at a product or even a code-base of a F/OSS project? /utorrent-sound-when-download-complete-mac.html. In today’s high-speed, fast-paced software industry getting something out quick and earning lots points at the end of a sprint, is becoming a mainstream practise these days. If you want to make sure you are sticking to your Software Craftsmanship motto: “We do not want to ship s**t” like Uncle Bob very rightly says – then you have gotta find a better way to streamline your development process to achieve just that!

That’s when tools like SonarQube ™ (formerly known as Sonar ™) come to our rescue or at least help us in the interim to get a better understanding of what software metrics and software quality can mean for your team! How to compare progress on a timeline and use it to get quick feedback to assess and improve the quality of the code we write and maintain is certainly an important thing to be able to do.

Installing SonarQube on a Mac OS X system hasn’t been as smooth as on systems with a Linux/Unix environment hence this blog. With some tweaks, assistance from third-party sites and following the do-s and don’t-s you should be able to get long and successfully install SonarQube and SonarQube Runner!

As installing and configuring SonarQube is an involved process, a number of items need to be taken into consideration and they have been categorised below under the various topics and sub-topics. Hopefully this makes the journey easier for all of us – since we have done it once and it has been a bit painful, its here for everyone else’s benefit.

Requirements

The below is a list of hardware/software installations are required to get success out of the instructions put together in this blog:

• Mac OS X Mountain Lion 10.8.4
• SonarQube 3.7 artefacts
• SonarQube Runner 2.3 artefacts
• MySQL 5.6.12
• JDK/JRE 1.7.0 or 1.8.0

Environment

These instructions have been performed on a system with the below configuration:

Model Name: MacBook Pro
Processor Name: Intel Core i7
Processor Speed: 2.3 GHz
Total Number of Cores: 4
Memory: 8 GB

HDD Capacity: 249.8 GB (SSD)

System Version: OS X 10.8.4
Java version: 1.8.0-ea-b103

Downloading, installing and configuring MySQL

A suitable MySQL binary can be downloaded from [01] or directly from [02].

Installing & configuring

MySQL must be present on the machine running SonarQube – which is the data store where all the relevant metrics per project are stored. To find out on how to go about installing MySQL on the Mac, please refer to the blog post How to install and configure MySQL on MacOS X for UTS [13]. The below window is an indication of a successful installation (System Preferences > Other > MySQL – blue icon at the bottom of the window):

Once the installation is complete, the create SonarQube database SQL script [14]will require to be run via the MySQL console or through another SQL client that can connect to the currently running MySQL server.

Command-line Interface (CLI)

There’s also a few other commands to know as part of daily MySQL operations:

Where MYSQL_HOME was set to /usr/local/mysql (check if it is the same in your case) in the respective bash configuration file.

In order to not perform the above command on a regular basis, ensure that the Automatically Start MySQL Server on Startup is switched on.

Check if the database has been created correctly, by performing the below commands on the CLI (look for the highlighted database, you will also need to enter the root password for your MySQL server here):

Installing & configuring JDK/JRE

Downloading, installing and configuring SonarQube

Downloading
Download the latest binaries from the SonarSource downloads site [04].

Installing & configuringJust another hand font download mac.

Unzip the archive into a folder of your choice for e.g. the /opt/ folder. Once done, set the SONAR_HOME environment variable to point to this location, in the respective bash configuration file:SONAR_HOME = /opt/sonar-3.7/

Source the bash configuration file and perform the below actions to ensure that SonarQube can connect with the available MySQL database:

1. comment the derby configuration
2. uncomment the mysql configuration,
3. save the changes and close the file.

Also note SonarQube’s JDBC credentials are:

By default the web port where SonarQube is listening, is set to 9000, which can be changed in the $SONAR_HOME/conf/sonar.properties file. Change the sonar.web.port property to another setting if port 9000 is being used by another application, i.e.

There’s one more place where this is defined and must be in sync with this file, see below in the settings.xml file – the line referring to …localhost:9000… which should be changed as well (to …localhost:9100… if the port settings in the $SONAR_HOME/conf/sonar.properties is also changed).

Install maven if it does not exists already (recent versions of the Mac OS X comes with maven installed), ensure it is included in system path i.e. PATH and run the below command at the CLI to verify this:

Check if the below maven options are set otherwise set the MAVEN_OPTS environment variable in the respective bash configuration files:

Finally put the settings.xml containing the below lines into the ./m2 folder (maven’s configuration folder):

(additional reference: Installing and Configuring Maven [05])

Upgrading SonarQube from the current 3.x.y to version 3.7

Upgrading to a newer version of SonarQube is as easy as downloading the latest binary and placing the expanded folder into the /opt/ folder or elsewhere on your system, updating the environment variables via the respective bash configuration files (see previous section).Restart SonarQube (see below section to know how to do that), wait for a couple of minutes, and finally run the database migration process by opening the below location via the browser and clicking on the Upgrade button:

…this should take few minutes and the databases should be migrated to the latest version.

Jdk1.7 Downloads For Windows10

Once finished, navigate to the web address http://localhost:9000/ to see the very familiar SonarQube dashboard (see below the screen-shot of the live SonarQube implementation i.e. Nemo[06]on as an example):

Once the dashboard has been been presented, log in by clicking on the Log in linkon the top right corner of the browser window with the below credentials:

Running SonarQube via the CLI

Starting SonarQube from the CLI with the below command:

or restarting it, if it is already running:

…stopping it is the same:

A few other parameters are available i.e. console, status and dump –SonarQube needs to be running in order for any of these to work, which you will find out very easily with the “sonar is not running.” message.

Note: MySql must be running when SonarQube is (re)started. In the above case it is assumed that SonarQube is installed in the /opt/ folder.


Download, install and configure SonarQube Runner

SonarQube can be setup to analyse projects through various ways, one of the other ways is to use SonarQube Runner, which requires a sonar-projects.properties file that would contain the basic definitions of the nature of the project. It is used in case the project to analyse is not maven project (does not have a pom.xml file).SonarQube Runner can be downloaded from the same location where the SonarQube binaries are kept [04].

Unzip the archive containing the binary for SonarQube Runner into a folder i.e. /opt/ folder and set the environment variable SONAR_RUNNER to this location in the respective bash configuration files.

Checking SonarQube or SonarQube Runner

Here are a couple of links to sample sonar-project.properties files to assisting in creating new ones i.e. Sonar setup for non-maven Java project [10] and Analyzing with SonarQube Runner [11].

Troubleshooting

In particular $SONAR_HOME/logs/sonar.log contains SonarQube specific system level log messages.

Tips

Always source the bash configuration files after amending them.
