问题
All the configuration information about debug and release modes are stored in .cproject file. But I don't find any information about which is the Active configuration in .project or .cproject file. Where can I find this information?
回答1:
It is stored in <workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/<project>/.indexes/properties.index, in a binary format.
