Tycho 编译器没有从插件依赖中找到类

Question

I am trying to build a plugin with Tycho. There are no errors in the Eclipse workspace, but when I try to compile it with Maven I got the following errors (more than 57 errors):

It seems like that Tycho compiler does not consider the plugin dependencies when it tries to compile: The type that is missing is defined inside the jar org.eclipse.xtext.xbase that is required in the MANIFEST.

Any ideas how to fix this problem?

Answer 1

When you enable debug output ( -X ), the log output of the tycho-compiler-plugin includes the exact list of JARs that Tycho compiles against. (Look for [DEBUG] Classpath: )

So if you eg see that Tycho's dependency resolution picked the wrong version of org.eclipse.xtext.xbase, you can either

• change the target platform so that only the version you want is included, or
• make the dependency declared in the MANIFEST.MF more restrictive.

In your example you specify with Require-Bundle: org.eclipse.xtext.xbase;bundle-version="2.4.3" that you want version 2.4.3 or later. But maybe this is wrong and you actually require a higher minimum version.

问题出在 org.eclipse.xtext.xbase 的版本上。
