Plug-in Compiler Preferences

Compilers preference page

Syntactic errors in plugin.xml, fragment.xml and MANIFEST.MF are all flagged as errors by the plug-in manifest compiler. As for semantic problems in the plug-in manifests, the severity for each problem category can be set to Error, Warning or Ignore.

Workspace vs. Project Settings

The plug-in compiler preferences are set at a workspace level on the Open the compilers preference page Window > Preferences... > Plug-in Development > Compilers preference page and take effect on all plug-in projects in the workspace.

It is also possible to override the workspace-scope settings by having compiler settings at the plug-in project level. To do so, select Properties from the context menu of a plug-in project. In the Properties dialog, project-level manifest compiler settings can be customized on the Plug-in Development > Plug-in Manifest Compiler preference page.
