MyEclipse build path to project is invalid

Today, we found that the project downloaded from SVN yesterday was unable to build path in MyEclipse. Tip No actions available

Found on the Internet, due to the problem of. projects file, you need to include some nature tags in the natures tag

These are some of the myeclipse configuration

<nature>com.genuitec.eclipse.ast.deploy.core.deploymentnature</nature>
<nature>com.genuitec.eclipse.j2eedt.core.webnature</nature>
<nature>org.eclipse.jdt.core.javanature</nature>
<nature>org.eclipse.wst.jsdt.core.jsNature</nature>

After the join is complete, set the default output folder in the build path

Typically the project name/webroot/web-inf/classes

Off-topic. CSDN should add another label. For example, the content part of the blog is original, but part of it is borrowed from others.
