Java Eclipse Java 构建路径添加项目 ClassNotFoundException

Question

I have a Java project, where I collect all my util classes and I want to use them in other projects. So I have tried to add the utils project to the Java Build Path of the project where I want to use the utils. But when I use them, I get a ClassNotFoundException at runtime, but no compile errors.

How can I solve this?

So in your ChunkPlots folder on you filesystem, look for a .classpath file and verify you have a line that looks like

<classpathentry combineaccessrules="false" kind="src" path="/BukkitUtils"/>

I've done something like this before and that line is in that file for me. I might have used the Libraries tab to add the project. I don't really remember and I don't use Eclipse anymore.
