In JBoss Devstudio, I am getting this new "error" with Tern: Synchronizing script resources with tern server. It's not really an error, but it's a process that occurs every single time I click in a JavaScript file. It's just spinning and freezes up the entire IDE. This has never happened to me before, and I was working on the project yesterday without any issues.

Does anyone know what the hell this is? There isn't really anything on Google except one post that says to upgrade.

    I have this problem also. I wonder about Help->Installation Details, and then UNINSTALL the `JBoss Tools Java Standard Tools Tern.java Adapter`. Will that fix the problem? – John Henckel Dec 12 '16 at 19:18

JBoss Devstudio integrates tern.java for JavaScript support. I think your problem is because that you have a lot of JavaScript files in your project (inside node_modules or bower_components) and tern.java tries to analyze your all JavaScript files, and it takes time.

In your case, you need to exclude folders like node_modules and to do that you must use a version of tern.java >= 1.0.0 which support include/exclusion pattern path.

  • This doesn't seem to work! I tried to set the exclusion path to `**/*.js` but it still fires up the Synchronize when I modify a JS file. How do I tell it to exclude **everything**? – John Henckel Dec 12 '16 at 19:20

To deal with this problem, open your workspace and drop the folder, like E:\eclipse\workspace\.metadata\.plugins\tern.eclipse.ide.server.nodejs.embed.win32.win32.x86_64, the node.exe in it is the point.

I resolved this issue by simply eliminating the built in js files from path.

  1. I removed this from validations '**/node_modules/*,**/bower_components/*'. (If it even didn't resolve)Go to Properties of the project > JavaScript > Include Path > Validation

OR

  1. 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.
