"Server Tomcat v7.0 Server at localhost failed to start" without stack trace while it works in terminal

1. Open the Servers Tab from Windows → Show View → Servers menu

5. Select the Apache Tomcat v7.0 server and remove it. This will remove the Tomcat server configuration. This is where many people do mistake – they remove the server but do not remove the Runtime environment.

6. Click on OK and exit the screen above now.

7. From the screen below, choose Apache Tomcat v7.0 server and click on next button.

8. Browse to Tomcat Installation Directory

9. Click on Next and choose which project you would like to deploy:

10. Click on Finish after Adding your project

11. Now launch your server. This will fix your Server timeout or any issues with old server configuration. This solution can also be used to fix “port update not being taking place” issues.

To resolve this issue, you have to delete the .snap file located in the directory:

<workspace-directory>\.metadata\.plugins\org.eclipse.core.resources

After deleting this file, you could start Eclipse with no problem.
