Restore maven plugin for a project on eclipse
提问by kunigami
I've disabled m2eclipse plugin for a project by clicking on "Disable Maven Nature" as shown in the Figure below. Then the Maven entry disappeared from the menu and I'm unable to restore it.
我已经通过单击“禁用 Maven Nature”来禁用项目的 m2eclipse 插件，如下图所示。然后 Maven 条目从菜单中消失了，我无法恢复它。
How do I restore/reset/re-enable so that the entry appears again?
如何恢复/重置/重新启用以便再次出现该条目？
PS 1: I'd like to do that without re-importing the project.
PS 1：我想在不重新导入项目的情况下做到这一点。
PS 2: I've looked in ${WORKSPACE}/.metadata\.plugins\org.eclipse.m2e.core.uiand ${WORKSPACE}/.metadata\.plugins\org.eclipse.m2e.corebut nothing seems related.
PS 2：我已经看过了${WORKSPACE}/.metadata\.plugins\org.eclipse.m2e.core.ui，${WORKSPACE}/.metadata\.plugins\org.eclipse.m2e.core但似乎没有任何关系。

Solution:
解决方案：
Go to the project menu (right click on Package Explorer) > Configure> Convert to Maven Project
转到项目菜单（右键单击包资源管理器）> Configure>Convert to Maven Project
This should restore the entry in the project menu.
这应该恢复项目菜单中的条目。
