问题
I have two pairs of projects that I develop in NetBeans, both of which have a GUI project, and a library project, where the GUI project depends on the library one. In one of them, NetBeans recognizes that the dependency is local, and indicates as such with an Ma symbol, as seen below, with the dependency project in green:
This provides some nice functionality, most notably that the "Navigate to" (ctrl+click) functionality from the GUI project takes me to the source code in the library project. I also don't have to manually rebuild the library project for the GUI project to pick up any changes.
However, for the other pair of projects, NetBeans will pick up that the dependency is in my local Maven repo, but does not recognize that the source code is a Maven project that it also has open:
I've tried looking through all the right-click menu options, removing and re-adding the dependency from the NetBeans GUI, comparing the pom.xml, comparing nb-actions.xml, and nb-configuration.xml, but cannot find any explanation of why one library is recognized as local, but the other is not. The only information I've found online is at http://wiki.netbeans.org/MavenBestPractices, where it notes:
"Hint: If you open a project that other projects depend on, the icon in other projects changes to a "maven project" icon to denote that the IDE knows about link between the projects. However such a link is only established when the groupId, artifactId and version all match in the dependency and project declaration. Frequently occurring problem is that you change an API signature in your library project, but the application is not picking up. Often it's caused by the fact that the application is using an older version of the library artifact. The artifact icon can help you track down these problems."
However, I've verified that the pom.xml of the GUI project depends on the version being built in the library project, and even made the versions identical between the GUI project and library, and the "maven project" icon still doesn't show up.
Does anyone know how to debug this issue, or if there's a magic setting somewhere that I'm missing for how to make this link work? I've been trying with both NetBeans 8.2 and 8.1, and am compiling with Java 8 for both the successful pair of projects, and the unsuccessful ones.
