Summary
This knowledge-base article covers a scenario where a build fails for a plan which was created via Java specs scan import ( via an IDE ). The plan has a SVN repository linked locally.
The import of the plan is successful but the build fails with java.lang.NullPointerException which is seen in the build logs.
Environment
The issue is seen on Bamboo 9.1.0 but it might be applicable for any other supported version of Bamboo.
Diagnosis
The first step towards diagnosis is to refer the Bamboo build logs for the plan which is failing, the logs point to java.lang.NullPointerException as seen below:

ERROR [7-DelayedChangeDetectionThread:pool-10-thread-4] [ChainExecutionManagerImpl] Errors getting changes for job-key
com.atlassian.bamboo.repository.RepositoryException: java.lang.NullPointerException at
com.atlassian.bamboo.v2.trigger.DefaultChangeDetectionManager.collectChangesSinceLastBuildInternal(DefaultChangeDetectionManager.java:443) ~[atlassian-bamboo-core-9.1.0.jar:?]
...
Caused by: java.lang.NullPointerException
at com.atlassian.bamboo.repository.svn.v2.AbstractSvnExecutor.getSubstitutedAccessDataBuilder(AbstractSvnExecutor.java:166) ~[atlassian-bamboo-core-9.1.0.jar:?]ℹ️ An interesting point to note is that the build works properly if the same repository is saved manually after import from Bamboo GUI by going to configure plan > repositories tab.
Cause
The cause of the issue is incorrect specs code for the repository section of the plan, it is missing the section for branch configuration and as per the error above, Bamboo is looking for the branch name and hence NullPointerException:

branchConfiguration(new MapBuilder()
.put("repository.svn.branch.displayName", "trunk")
.put("repository.svn.branch.path", "")
.build())
.changeDetectionConfiguration(new VcsChangeDetection()))Solution
The solution is to combine the above 2 sections as described in the cause section above for the specs and reimport the Java specs, kindly refer below
