Description:

Runs the project with a debugger port hook (optionally suspended).

Attributes:

  • Requires a Maven project to be executed.
  • Executes by direct invocation only.
  • Requires dependency resolution of artifacts in scope: test.
  • Invokes the execution of the lifecycle phase process-classes prior to executing itself.
  • Invokes the execution of this plugin's goal war:exploded prior to executing itself.

Required Parameters

Name Type Since Description
generateDirectory File - Folder where generated-source will be created (automatically added to compile classpath).
Default value is: ${project.build.directory}/generated-sources/gwt.
