= ProblemsWithEclipse = '''Message: Working copy not locked; this is probably a bug, please report svn: Working copy 'C:\workspace_beta\DFKIUtils2\lib' is missing or not locked''' solution: '''Compile errors because required libraries are missing''' So, after updating some libraries do not check-out from the SVN. solution: * see if libraries are online 'https://gnowsis.opendfki.de/repos/gnowsis/branches/gnowsis0.9/'. * update * replace with latest from repository * If you don't have the libraries after "update" or "repace with latest from head", you are doomed. * delete your Eclipse Project (also delete contents) and do a new check 'out as project' To do this: you can rightclick on the project and do replace with latest from reository which is pretty much the same as above, you you can do this just for the folder with missing files.
