gwt:debug

Full name:

org.codehaus.mojo:gwt-maven-plugin:2.7.0:debug

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.
runTarget String - URL that should be automatically opened in the GWT shell. For example com.myapp.gwt.Module/Module.html.

When the host page is outside the module "public" folder (for example, at webapp root), the module MUST be specified (using a single <module> in configuration or by setting -Dgwt.module=..) and the runTarget parameter can only contain the host page URI.

When the GWT module host page is part of the module "public" folder, the runTarget MAY define the full GWT module path (com.myapp.gwt.Module/Module.html) that will be automatically converted according to the rename-to directive into renamed/Module.html.


User property is: runTarget.
webXml File - Source web.xml deployment descriptor that is used for GWT shell and for deployment WAR to "merge" servlet entries.
Default value is: ${basedir}/src/main/webapp/WEB-INF/web.xml.

Optional Parameters
