Answer 1

I ran into this annoying issue with the Play framework. It would be nice if there was some way of knowing what build errors Eclipse is unhappy about, but it's not going to tell you. With one project, I was able to close the project, rebuild the Eclipse configuration with sbt eclipse, and reopen. With an almost identical project, that didn't work. But deleting the project, rebuilding the Eclipse configuration with sbt eclipse, and importing, did the trick.

Go to > Right CLick on your project folder > Build Path > Configure Build Path > Libraries Tab > remove project and external dependencies > apply & close

Now, Gradle refresh your project.

Answer 3

This what fixed it for me...

I was having an issue with my spring-core.jar. I deleted the entire release directory located here. (I'm on win 10).

C:\Users********.m2\repository\org\springframework\spring-core\4.3.1.RELEASE

I right clicked on the project > Maven > Update project and my exclamation mark disappeared. No problems any more.

Here is the source where I found the information:

Answer 4

None of the other answers worked for me. Even after fixing my build path issues, doing a refresh, clean, rebuild, and restart (of both eclipse and the computer), I was still getting the little red exclamation point.

I fixed it by closing the project (right-click, close project) and reopening it (double-click the closed project), which seemed to force eclipse to "notice" that the build path problems had been corrected.

Answer 5

just check if any unnecessary Jars are added in your library or not. if yes, then simply remove that jars from your library and clean your project once. Its worked for me.

Answer 6

In Eclipse this worked for me: right click project. -> Properties -> Library Section; Add (any library at all) -> select library and click remove -> press okay.
