Spring Tool Suite not completing sources and javadoc download

I have STS 4.11.1.RELEASE installed.

On the bottom right corner there's this message that keeps blinking and never stops:

"Download sources and javadoc: (66%)"

The message has been there for days.

Have restarted STS and the computer several times and that blinking message keeps there.

For some reason the download is not completing.

Have already added SpringToolSuite4.exe to the Windows Defender (which is the antivirus/firewall I'm using) allowed files list.

Have also tried completely turning off Windows Defender with no result as well.

Martin seems to be right. The problem seems to be caused by a corrupted local Maven artefact stored on your hard drive in the Maven cache.

Steps to fix are just to refresh your Maven cache by removing the repository directory.

  1. Close eclipse (This step is required more on Windows due to file locking).
  2. Delete your ~/.m2/repository/ directory (On Windows it's under C:\Users\<your user>\.m2\repository\).
  3. Open eclipse.

If you want to backup the cache by moving it instead of deleting then use this:

# To clear the Maven (m2) cache:
mv -v ~/.m2/repository{,_bak}

# To restore if required:
mv -v ~/.m2/repository{_bak,}

# To delete the backup once you're sure you don't need it:
rm -rf ~/.m2/repository_bak

Once eclipse is launched it will re-download the Maven dependencies of all your projects from scratch into a new ~/.m2/repository/ directory. This may take some time depending on the number of dependencies and your internet speed. You can see the progress of the downloads in the progress pane.

Once it's done the progress pane should no longer repeatedly show "Download sources and javadoc".
