I use Eclipse Luna SP2 for Java EE for some JavaScript development. Every now and then (mostly on .js file open but also on some timer) I get the following popup error

    An internal error occurred during: "Synchronizing script resources with Tern server...".
    loader constraint violation: loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) 
previously initiated loading for a different type with name "org/apache/http/HttpEntity"

I don't need Tern functionality and I would like to disable it or at least get rid of the popup error

I googled about but could not find any relevant information. For the moment I tried to disable all validators and to change the .js editor but no luck by now.

Any idea?

I think it's the same problem than issue 273 The 0.8.0 didn't set the version of packages of org.apache.http in the MANIFEST.MF.

Please install 0.10.0 version.

Go to Properties of the project > JavaScript > Include Path > Source and remove the whole project. Click on "Add Folder" and give the required path for your JS. Like projectname/src/pages.Ionic 2
