Describe better what you are trying to do: Modify the POM of a Maven project, or modify what the IDE thinks is the classpath of it so it offers completion for some more stuff?
For the former, there's - Have an implementation dependency on the Maven module, and call code internal to it - Depend directly on Maven and use Maven's goshawful API for that sort of thing - Find the pom file, analyze it and rewrite what you need (carefully, and checking parent poms!) - for me, this was the least painful and least likely to break option For the latter: - Assuming you want to expose a folder under src/main on the classpath, implement LookupProvider (not Lookup.Provider!), and register it against the maven project type, e.g. @LookupProvider.Registration(projectTypes = @LookupProvider.Registration.ProjectType(id = "org-netbeans-modules-maven")) - In the lookup that returns, put an object that implements (from the Maven module's unofficial API - use Yenta) OtherSourcesExclude and JavaLikeRootProvider to *remove* that source folder from the ones it will detect as "other sources" (if you skip this step all hell breaks loose) - Also include in that lookup your own implementation of Sources which returns some additional folders when SourceGroup[] getSourceGroups(String type) is called with "java" - that should allow the ClassPathProvider in the project to pick it up (and will get you your own "sources" node under the project) -Tim On Tue, Sep 10, 2019 at 2:50 PM joe schmo <geekyguy...@hotmail.com> wrote: > Does anyone know how to add a directory to the classpath in a Maven based > project in NetBeans 11.1? > > Thanks > > > -- http://timboudreau.com
