Hi momyyao,
Can you try steps given below:
1) Go to “Window–>Preferences–>MyEclipse–>Maven4MyEclipse” and select Maven.
2) Check the checkboxes “Download Artifact Sources”, “Download Artifact Javadocs” and “Download repository index updates on startup”.
3) Create a web project and add Maven support.
4) Wait for few minutes and check whether you got some entries on “Select goal” dialog.
Note: You need to have internet connection connected to your system.
Please let me know whether the above mentioned steps resolved your problem.
Thanks,
Chakri Vedula.
