| [platform-ui-dev] Issue with org.elipse.e4.ui.progress |
|
Hello,
i'm currently working on an eclipse e4 project. I want to use the ProgressView in my project. First of all i followed the instructions as shown on: https://wiki.eclipse.org/Eclipse4/ProgressView to
install the Plug-In. After a long time searching why the addon is not loaded i found the solution. The problem is the version of the artifact on: https://hudson.eclipse.org/platform/job/eclipse4-progress-view/lastSuccessfulBuild/artifact/releng/org.eclipse.e4.ui.progress.update/target/repository/ is
not the newest version. The actual error is that the manifest file of the artifact contains a version for the imported-package javax.annotations. This causes that the Add-On is not loaded on adding it to the Project (it
would be great if you could update the artifact on the hudson repository). After figuring this problem out I resolved it by cloning the newest version of the Plug-In into my
workspace.
But I'm still facing more issues. Currently I'm getting InjectionException in the ProgressViewAddon caused by a NullPointerException in the Services.class (whole stacktrace below). The problem is the injected fields are all null in the Service class.
Also in the other classes like Preferences or PreferencesStore the Fields with the @Injected annotations are null (I debugged through the code and saw that, but the MApplicaiton and IEclipseContext injected in the init method are both not null).
Because of the problem appearing in all other classes I'm currently thinking that I made some errors setting up the environment. So I have an product file which contains the org.eclipse.e4.ui.progress plug-in on start level 0 with auto-start=true. In the
manifest of my plug-in I added the org.eclipse.e4.ui.progress as an required Plug-In. In the application model (e4xmi file) I added an Add-On with the Class-Uri: bundleclass://org.eclipse.e4.ui.progress/org.eclipse.e4.ui.progress.ProgressViewAddon. I also
added the ProgressView as a part. Did i forget something or is just something false configured on my application?
So I hope somebody could help me with this error.
