I am using the Google Plugin for Eclipse to deploy my project to App Engine, and this has worked great for over a year. But a couple of days ago it stopped working, and I can not seem to find the reason. The project is still an App Engine project, but the Deploy to App Engine button is disabled.

I already reinstalled the entire Google Plugin in Eclipse. I also added another GAE project, but then the button is still disabled. I managed to enable the button once to upload, but I don't know what triggered the enabling.

enter image description here

Has anyone seen this before and any clue on how to fix this?

EDIT: The button enabled when I removed and re-added the App Engine SDK from the build path of the project. After the deployment, the button disabled again..

This is a known bug in the latest 3.9.1 release. The fix will be pushed on Monday, 5/2.

The same thing is happening for my eclipse mars. The workaround I'm using is, File >> Close Project, then double click to open project, voila.

The "Deploy to App Engine" only disables itself when I select another project. So to get it enabled:

  1. Deselect all projects (Ctrl+Click on the selected project - or restart Eclipse).
  2. Select your project.

It should then be enabled (well, it was for me).

EDIT: Google rolled out a new version of the plugin, and now the button works fine.

For those who don't want to wait (I didn't), use appcfg. If you want to use External Tools, you'll find the executable in (SDK install - check configured SDK's)/bin/appcfg.(sh|cmd)

Set the working dir to the project folder, the commands are "update war", where 'war' is the location of the war directory relative to the project folder.

I set JAVA_HOME under the environment tab to the Java SDK, and PATH to the Java SDK/bin directory, and "replace native environment with specified environment" on Windows, worked fine without Environment settings on Linux.

Running Eclipse Neon 4.6.3 with no issue. To get it enabled:

  1. Install Google Cloud SDK and Cloud Tools for Eclipse https://cloud.google.com/eclipse/docs/quickstart
  2. Install components using the Google Cloud command line
    • gcloud components install app-engine-java
  3. Convert eclipse project to a google app engine project
    • Right-click on project
    • Click on Configure
    • Click on Convert to standard app engine project
  4. Make sure you click on the project and... voila!

For me simple restarting of the eclipse did the trick.

I had closed the project by mistake and when I re-opened it, the deploy button was disabled.
