Missing maven package from idea.jar
已回答
I wanted to match width for MavenView
(as in my last post https://intellij-support.jetbrains.com/hc/en-us/community/posts/360002399299-Project-view-list-of-files-packages)
I've found some interesting classes on intellij github repository that may help me, but it looks like my idea.jar is missing this package.

1. Is there a way to include this package?
2. Or is there another way to access Maven View(read its content and change it's width)?

Any advice ?

It seems <depends> with Maven Plugin ID wasn't added in your plugin's plugin.xml?
Yea I realized it. Thanks!
