Eclipse/STS does not suggests autocompleting for JUnit code-CodePudding

I have a simple project configured with the pom.xml file that I copy below. The problem is that Spring Tool Suite 4.9.0.RELEASE does not suggests automplete for classes nor methods from JUnit library. If I write code like this one:

Assert.assertEquals(text_1, text_2);

It compiles and works, but if I put the mouse cursor right after the dot after Assert and press Ctrl . "No default proposal" message is shown. With other classes out of JUnit autocomplete suggestions works fine.

I checked configuration as proposed in other questions but none fixes this issue.

CodePudding user response：

Removing .metadata and .settings folders along with .project and .classpath files seems to have resolved the issue (in addition to reboot Eclipse and import projects again).

This way I also lost launch configurations, etc.
