apt not work in jdk > 9

This is because of the bug1 and bug2. Although it can be fixed immediately by the eclipse team, I think they will not fix it. The bug2 was reported 7 month ago and two new version released. A workround is using processormodulepath instead of processorpath. ( Perhaps introduce side effect. ) However, the maven does not support processormodulepath option. So the workaround should be placed in the plugin.
For example the plugin provide an option to decide whether processorpath should be replaced with processormodulepath.
