buildcommands List List of eclipse build commands. By default the org.eclipse.jdt.core.javabuilder builder plus the needed WTP builders are added. If you specify any configuration for this parameter, only those buildcommands specified will be used; the defaults won't be added. Use the additionalBuildCommands parameter for that.

When this flag is true remote repositories are checked for javadocs: in order to avoid repeated check for unavailable javadoc archives, a status cache is mantained into the target dir of the root project. Run mvn:clean or delete the file mvn-eclipse-cache.properties in order to reset this cache.
downloadSources boolean Enables/disables the downloading of source attachments. Defaults to false. When this flag is true remote repositories are checked for sources: in order to avoid repeated check for unavailable source archives, a status cache is mantained into the target dir of the root project.

Additionally it copies all libraries to a project local directory and references them instead of referencing the files in the local Maven repository. It also ensured that the "Bundle-Classpath" in META-INF/MANIFEST.MF is synchronized. Default value is false.

</projectnatures>
skip boolean Skip the operation when true. Default value is false.
workspace String This eclipse workspace is read and all artifacts detected there will be connected as eclipse projects and will not be linked to the jars in the local repository. Requirement is that it was created with the similar wtp settings as the reactor projects, but the project name template my differ. The pom's in the workspace projects may not contain variables in the artefactId, groupId and version tags.
wtpContextName String JEE context name of the WTP module. ( ex. WEB context name ).
wtpapplicationxml boolean Must the application files be written for ear projects in a separate directory. Default value is false.
wtpdefaultserver String What WTP defined server to use for deployment informations.
wtpmanifest boolean Must the manifest files be written for java projects so that that the jee classpath for wtp is correct. Default value is false.
wtpversion String The version of WTP for which configuration files will be generated. The default value is "none" (don't generate WTP configuration), supported versions are "R7", "1.0", and "1.5" Default value is none.
