Symptoms

When bamboo executes a MSBuild plan the build log shows the following error;

1 2 3 4 Failed to execute the build 'MY-BUILD-42' java.lang.ArrayIndexOutOfBoundsException: 1 at com.atlassian.bamboo.plugin.builder.nant.AbstractDotNetBuilder.getEnvironmentSetting(AbstractDotNetBuilder.java:360) at com.atlassian.bamboo.command.Command.executeCommand(Command.java:61)

Cause

If the plan's builder configuration sets a variable like PATH=C:\bea\;%PATH% the existing Path variable is overridden.

Resolution

  1. Delete this variable from the build configuration and try re-running the plan.

  2. Substitute %PATH% with ${system.PATH}
