Eclipse tomcat does not start – May be locked by another process.

Happy Western New Year 2019!

I had a single spring web project. It became too big over the day. I had to split it up into multiple reusable projects so that I can build APIs. After I split it, Tomcat refused to start with the following error.

Publishing failed with multiple errors
Could not delete D:/Pandian/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/crm-upload/WEB-INF/lib. May be locked by another process.
Could not delete D:/Pandian/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp1/wtpwebapps/crm-upload/WEB-INF. May be locked by another process.

I tried to clean work folder, It doesn’t work. I did the following sequence to resolve this.

  1. Remove the tomcat server from eclipse server tab
  2. Restart Eclipse
  3. Add a new tomcat server
  4. Start the project
