Tycho 编译器未从插件依赖项中找到 类
Tycho compiler does not find classes from plugin dependecies
我正在尝试使用 Tycho 构建一个插件。 Eclipse 工作区中没有错误，但是当我尝试使用 Maven 编译它时出现以下错误（超过 57 个错误）：

似乎 Tycho 编译器在尝试编译时没有考虑插件依赖性：缺少的类型在 MANIFEST 中所需的 jar org.eclipse.xtext.xbase 中定义。
有解决此问题的想法吗？
问题出在 org.eclipse.xtext.xbase 的版本上。
当您启用调试输出 (-X) 时，tycho-compiler-plugin 的日志输出包括 Tycho 编译所针对的 JAR 的确切列表。 （寻找 [DEBUG] Classpath:）
所以如果你看到 Tycho 的依赖解析选择了错误的 org.eclipse.xtext.xbase 版本，你可以
- 更改 target platform 以便仅包含您需要的版本，或者
- 使 MANIFEST.MF 中声明的依赖项更具限制性。
在您的示例中，您使用 Require-Bundle: org.eclipse.xtext.xbase;bundle-version="2.4.3" 指定您需要 2.4.3 或更高版本。但也许这是错误的，你实际上需要更高的最低版本。
