我有Eclipse LUNA,现在想要安装ObjectAid制作UML图。但是当我尝试安装时,会出现以下错误:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.java, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Artifact osgi.bundle,org.junit,3.8.2.v3_8_2_v20100427-1100 is a folder but the repository is an archive or remote location.
为什么我会出现这个错误,如何克服它?
谢谢
