Build Identifier: 20110916-0149 Hi, When I try to search references (in project or workspace), Eclipse found 0 references and return me (in the search pannel) the message "0 references in workspace (no JRE)". I'm on a large project, imported from a svn repository with a subclipse checkout. I'm using a .classpath from someone else (so, not the original created by Eclipse). This problem happen in "separate folders for src & class" mode and in "project folder as root for src & class" mode. An other detail : in the "Select Main Type" dialog for Main class selection (in Run Configurations), I didn't have the class I would to use. Now it appearing, but I don't know how/why. Is it a bug ? Or something else with a not really clear error message ? Reproducible: Always
The "no JRE" is not a message but simply indicating that it did not search the JRE. Your problem looks like a wrong Java build path. Make sure - you don't have build path errors on your project - all folders that contain code are on the Java build path
https://github.com/eclipse-jdt/eclipse.jdt.ui/issues/508 raised to clarify the "No JRE" text. I encountered a similar problem of no matches from perhaps just one plugin. It eventually went away after a clean-all restart clean-all.
