I think I screwed up my Eclipse installation while trying to install Apache Commons…
It is showing scary things like this, with little help on what to do…


The weird thing is I didn’t really do anything apart from copying commons-lang3-3.1.jar into the folder with all the other jars I’m using…
What could I have possibly done and how can I possibly fix this? Please help
Looks like jre link to eclipse is broken.Right click on the project go to
BuildPath -> Configure Build Path -> Libraries -> Add Libraryand SelectJRE System Library. Now select thejrefolder of your installed Java location and refresh the project. This should solve the issue. Alternatively you can createsoftlinktojrefolder inside the eclipse folder in case of Linux OS.
