In order to build WSO2 products from the Source distribution, it is necessary to install Apache Maven on Windows.
Apache Maven v.2.1.0 or later is recommended for WSO2 products
Refer to Installation Prerequisites for the list of all applications necessary to install and work with the WSO2 product you plan to install.
Follow the instructions below to set up Apache Maven.
Make sure you have a JDK installed on your system. Refer to Apache Maven System Requirements for details.
1. Open a Web browser and access the following URL:
2. Apache Maven home page opens. Click the "Download" link in the "Get Maven" section.
3. The link redirects to the storage page of different download pack versions. Choose the version suitable for Windows.
4. The link redirects to the page suggesting a mirror site for the download. Follow the link on the page.
5. The download Save dialog box opens. Click "OK."
6. The download starts.
After the download is complete, extract installation files to the user-defined folder. For example,
In order to run Apache Maven, it is necessary to set up
M2_HOME environment variable, and add "bin" to
PATH variable. The variable points to the directory where Apache Maven is installed on the computer.
Environment variables are global system variables accessible by all the processes running under the operating system.
In order to set the variable, it is necessary to know the Maven installation folder. Using a browser (e.g. Total Commander) open the user-defined directory to which Apache Maven archive was extracted (See Step 2). This is the path to Apache Maven installation folder.
Follow the instructions below.
1. Right-click the "My Computer" icon on the desktop and select "Properties" from the pop-up menu.
2. In the "System Properties" window, go to the "Advanced" tab and click "Environment Variables".
3. The "Environment variables" window opens. Click the "New" button under "System variables."
4. The "New system variable" input box opens. Type "variable name": M2_HOME, and "variable value": Maven installation directory.
For example, c:\wso2\apache-maven-3.0.3. Click "OK."
5. In the "System variables" field select "PATH" and click on the "Edit" button.
6. The "Edit system variable" dialog opens. Add "<M2_HOME>\bin" without quotes to Variable value, where <M2_HOME> is the Maven installation directory.
For example, c:\wso2\apache-maven-3.0.3\bin.
7. Apache Maven set up is complete successfully.
Make sure that the system variable JAVA_HOME is set to the JDK location.
Follow the instructions below to verify that Apache Maven is set up correctly.
1. Open Windows command prompt (CMD). Click "Start" > "Run" and enter "cmd" without quotes and click "OK" to access CMD.
2. In the opened CMD window, type the following command and press <Enter>:
3. Information on current version of Apache Maven and M2_HOME location is displayed. For example,
If it is needed to set up variables only for the user currently logged in, JAVA_HOME should be set up in "User Variables" (the same way as in "System variables"). These changes will not affect any other users.
Variable set up will be effective for the CMD opened after this operation. In case a CMD had been run before the variable was set up, this change is not effective for it. To ensure the variable set up is effective, and variable value is reset, close and reopen the CMD you will run the WSO2 product from, or close and reopen the browser (e.g. Total commander) you are going to run the CMD from.
Once Apache Maven is properly set up, you can start building the WSO2 product from the source distribution.
