I am trying to run jira application on my local machine with atlas-run and atlas-debug command. But i have a build failure here.

[ERROR] Failed to execute goal com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.1:run (default-cli) on project ccd_jirautils: Execution de
fault-cli of goal com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.1:run failed: Unable to load the mojo 'run' in the plugin 'com.atlassia

xception: com/atlassian/maven/plugins/ampsdispatcher/AmpsDispatcherRunMojo : Unsupported major.minor version 52.0

I tried to run the same on Linux machine i am able to get the success build with the jre 1.7 and atlassian_sdk version 5.0.3. when i am trying to run the same on Windows platform i get the above error. I also tried with jre 1.8 which is a bigtime failure jira refuse to start. so please I need your help here. can you please suggest me what might be the solution for this?

Following are the major versions of JRE the class file is compatible with

Java SE 9 = 53
Java SE 8 = 52
Java SE 7 = 51

Check what version of JAVA does your MAVEN is using mvn -version. You should be using jre 1.7

  • I am explicitly setting the java version for jira application and it is running on 1.7 jre. Apache Maven 3.2.1 Maven home: C:\xxxxx\xxx\atlassian_sdk\6.2.2\apache-maven-3.2.1 Java version: 1.7.0_75, vendor: Oracle Corporation Java home: C:\xxxxx\xxx\java\1.7.0_75w64\jre OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows" – prb_cm Sep 22 '16 at 14:30
  • Any other solutions that i can try implementing? – prb_cm Sep 26 '16 at 14:11

You didn't mention the Jira version you're running, but the error, as mentioned by ravthiru comes from a Java version mismatch. That is you have to use Java 8 for this to work, at least if you stick to the atlas-run and atlas-debug scripts, which use the mentioned com.atlassian.maven.plugins:maven-amps-dispatcher-plugin:6.2.1 which is a bit odd, as that one is included in the plugin-sdk 6.2.2, maybe you updated the sdk? Would you mind having a look inside atlas-run and double check it's 5.0.3?

That plugin was compiled using Java 8, so you either have to do so too or use an older version of the atlassian-plugin-sdk, which was compiled using Java 7. The 5.x versions should work.

Regarding the failure of running Jira with Java 8: Which version are you running, and what errors does it log?
