Building Jira from source

Commercial users at any level receive access to Jira's source code (note, evaluation license holders are not permitted access to Jira's source code). This topic explains how to build this source code into a deployable Jira application.

Building all of Jira from source is only necessary if you need to make extensive modifications to Jira's source code and are using a WAR approach.

You should not need to rebuild Jira if:

• You need to change many JSP files. JSP files are the template files for many Jira webpages. They can also be more easily changed directly in the standalone Jira installation directory.
• Create a Jira plugin that adds functionality to Jira. For more information, read the Jira Plugin Guide. Changes and enhancements to Jira's functionality can often be made with Jira plugins without requiring core Jira source code modifications.
• Recompiling a small number of source files can be done using the instructions in the standalone external-source directory.

Before you begin

• Be aware that the procedures described on this page are not included in our Atlassian Support Offerings and consequently Atlassian cannot guarantee support for them. This material is provided for your information only and using it is done so at your own risk.
• The following instructions were tested for Jira 7.4.0.
• There is a known issue where the Workflow Designer source is missing from the Jira source code (see JRA-29615) - please keep this in mind when building Jira from source.

Building a Jira WAR file from a Jira Source release

1. Ensure you have JDK 1.8 or higher.
2. Download Maven 3.2.5 or higher from the Apache archives of the Maven website.

3. Ensure the JAVA_HOME environment variable is set and points to your JDK installation. For example,
   On Windows:

   1

   > set JAVA_HOME=[your JDK installation directory]

On Mac/Linux:

1

export JAVA_HOME=[your JDK installation directory]

4. Extract Maven to an appropriate location on your operating system. For example,
   On Windows, extract to:

   1

   C:\apache-maven-3.2.5

   On Mac/Linux, extract to:

   1

   /usr/local/apache-maven-3.2.5

5. Add Maven's bin directory to your path. For example,
   On Windows:

   1

   > set PATH=C:\apache-maven-3.2.5\bin

On Mac/Linux:

1

export PATH=$PATH:/usr/local/apache-maven-3.2.5/bin

Third-party libraries

Install all of the following restricted third-party (.jar) libraries to your local Maven repository (.m2), ensuring that you download the version specified below. All of these libraries are required to successfully build Jira from source. If any of these libraries are missing, the build process will fail.

To install the libraries, download each one of them (using the links above) into a directory on your file system, for example downloadsin your home directory area.

• For jmxri and jmxtools:

  • On Windows:
    Open the downloads directory and extract the jmxri.jar and jmxtools.jar files from the jmx-1_2_1-bin\lib subdirectory of the downloaded jmx-1_2_1-ri.zip file.

  • On Linux:

    1
    2

    cd $HOME/Downloads
    unzip jmx-1_2_1-ri.zip jmx-1_2_1-bin/lib/jmxri.jar jmx-1_2_1-bin/lib/jmxtools.jar

• For jndi:

  • On Windows:
    Open the downloads directory and extract the jndi.jar file from the lib subdirectory of the downloaded jndi-1_2_1.zip file.

  • On Mac/Linux:

    1
    2

    cd $HOME/Downloads
    unzip jndi-1_2_1.zip lib/jndi.jar

• For jta:

  • On Windows:
    Open the downloads directory and rename the jta-1_0_1B-classes.zip file to jta-1_0_1B-classes.jar.

  • On Mac/Linux:

    1
    2

    cd $HOME/Downloads
    mv jta-1_0_1B-classes.zip jta-1_0_1B-classes.jar

1. Download the Jira Core source archive from our Core source downloads page. To download Jira Software, go to Software source downloads.

2. Extract the Jira source archive to a location of your choice

   This will create a Jira source directory with the name atlassian-jira-X.Y.Z-source, where X.Y.Z is your version of Jira. For example, C:\atlassian-jira-7.4.0-source.

3. In the Jira source directory, create the localrepo directory. 

4. Set appropriate permissions for installing the node modules. In your Jira source directory, enter the following commands:

   Code block

   1
   2
   3

   chmod a+x jira-project/conf/frontend/node
   chmod a+x ./jira-project/jira-components/jira-plugins/jira-post-upgrade-landing-page-plugin/src/main/frontend/bin/node
   chmod a+x ./jira-project/jira-components/jira-webapp/src/main/resources/johnson-page/bin/node

5. Install libraries into your local Maven repository. In your Jira source directory, enter the following commands:

   1
   2
   3
   4
   5
   6

   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=javax.jms -DartifactId=jms -Dversion=1.1 -Dpackaging=jar -Dfile=$HOME/Downloads/jms-1.1.jar
   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=com.sun.jmx -DartifactId=jmxri -Dversion=1.2.1 -Dpackaging=jar -Dfile=$HOME/Downloads/jmx-1_2_1-bin/lib/jmxri.jar
   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=com.sun.jdmk -DartifactId=jmxtools -Dversion=1.2.1 -Dpackaging=jar -Dfile=$HOME/Downloads/jmx-1_2_1-bin/lib/jmxtools.jar
   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=jndi -DartifactId=jndi -Dversion=1.2.1 -Dpackaging=jar -Dfile=$HOME/Downloads/jndi.jar
   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=jta -DartifactId=jta -Dversion=1.0.1 -Dpackaging=jar -Dfile=$HOME/Downloads/jta-1_0_1B-classes.jar
   mvn install:install-file -Dmaven.repo.local=localrepo -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.1 -Dpackaging=jar -Dfile=$HOME/Downloads/ojdbc7.jar

6. Build Jira by executing the following Maven 2 command:
   On Windows:

   1

   C:\atlassian-jira-7.4.0-source\> build.bat

   On Mac/Linux:

   1

   > build.sh

7. A WAR file called jira-webapp-dist-X.Y.Z.war (where X.Y.Z is your version of Jira), will be built in the jira-project/jira-distribution/jira-webapp-dist/target subdirectory of your extracted Jira source directory. 

   For example, if the subdirectory created above (Extract the Jira source archive to a location of your choice) was C:\atlassian-jira-7.4.0-source, the WAR file will be found in:
   C:\atlassian-jira-7.4.0-source\jira-project\jira-distribution\jira-webapp-dist\target\jira-webapp-dist-7.4.0.war

8. The WAR file generated can now be installed into your application server to run the Jira application you just built.

Obtaining the source of Jira's dependencies

When building Jira from source, Maven will automatically fetch the binary (compiled) dependencies that it requires during the build process, so you don't have to do it manually (with the exception of the third-party libraries mentioned above (Third-party libraries)).

It is worth noting that Jira's source distribution not only ships with Jira's source code, it also includes the source of the internal Atlassian projects that Jira depends on (e.g. atlassian-bonnie, atlassian-core, etc.). The internal Atlassian dependencies for Jira's source distribution are made available as Maven-based archives. There will be a Maven-based archive for each dependency, named <dependencyname-version>-sources.jar. The only buildable part of the source package is Jira itself, not its dependencies.

Other dependencies are available on Atlassian's public repository. The source of these dependencies is usually available on the library's website (try googling for the library name), or can be identified in the SCM information of the relevant library.

If you have any questions regarding the build process, try searching/posting to the Atlassian Community, which is monitored by the development community, and by Atlassian as often as possible.
