Adding a project library to a module automagically...

I am having the same problem. I would be interested in any suggestions as well.

Or have you found a solution in the meantime, Daniel?

Hi,

No, unfortunately I have not found any solutions, and have put that portion of the plugin to one side until I can find some more information.

I will post anything I find to this thread.

Cheers,

The problem is that you add jar file from the LocalFileSystem. In this file system this is merely a file. Instead we need to create a library root inside the jar in order to be able to explore its contents. So the procedure of obtaining a VirtualFile is as following

String url = VirtualFileManager.constructUrl(JarFileSystem.PROTOCOL, ]]>) + JarFileSystem.JAR_SEPARATOR;

VirtualFile jarVirtualFile = VirtualFileManager.getInstance().findFileByUrl(url);

The jarVirtualFile.getFileSystem() will return a JarFileSystem instead of LocalFileSystem. Note also that when constructing the url, the path to jar file should have forward slashes ('/') as a file separator:
"C:/work/lib/mylib.jar"

Hi Eugene

Thank you very much for your answer and also for your explanation. It works very smoothly now!

You are welcome :)

hi ...

i have a somewhat related question...
i want to check if a project-library is selected in an module.
there must be an api i think, because the library settings screen shows the checkmarks.

can you give me a hint??

thanks

There's a LibraryTableRegistrar class:
com.intellij.openapi.roots.libraries.LibraryTablesRegistrar
You ca use its methods to obtain library tables of various "levels" (application, project, module, or a custom level)

Hello Eugene,

thank you.

now i use the ModuleRootManager to obtain a module and from that module i fetch the
OrderEntries. These entries i search for LibraryOrderEntrys on project level. That seem to be the
currently selected libraries of a module.

Is this the best way?

thanks

Depending on what you need. If you need to answer the question "what project-level libraries are currently attached directly to the module", then this is the right way. Don't forget that the libraries can be "exported" by a module and thus visible to modules that depend on this module.

ok cool ...
what i mean by checked is: a library is visible in the libraries pane (e.g. at project libraries) and checked there (contributing
to the classpath of the module)

i want to use this function in a very simple maven pom dependency <-> irida classpath sync plugin.
so i think im ok when i dont check the transitive module dependencies.
but just for the curiosity .. does some helper class exist that answers the question is a library with the name xyz in the classpath of a module?

thanks again for the real fast answer

No there's no such helper...

Hi ...
here is another question in the context of librarytable:
i want to create a library on module level.
i have no problems anymore with libraries on project-level.
i can simply create them with the library table that i can get via project.getComponent(LibraryTable.class). But i seem not to be able to get the library table for the module-level libraries (first try was to call getComponent on a module).
second take was the LibraryTablesRegistrar#getLibraryTableByLevel but i dont seem to get to the module-table.
another possibility would be to add the library directly as a LibraryOrderEntry. But i dont know how to create an object implementing this interface.
