在Eclipse中使用Maven构建C++

Question

我的项目包含多个Java项目，一个作为桥梁的Java-JNI-C++项目和一个保持算法库的纯C++项目。我已经成功编写了所有3种项目类型的Maven构建配置。因此，当我在命令行上（Windows 7，64位）调用它们时，一切都很顺利。

我不使用任何make文件或类似的东西。我使用exec-maven-plugin来调用我的mingw 64位安装（没有使用cygwin，而且我也没有知ingly安装msys）。因此，对于JNA和Library项目，每个都有2个纯命令行g++命令。

现在，我需要一个平滑的开发工作流程，可以使用maven构建脚本从Eclipse内部构建和调试这些项目，因为我不想在我的pom中投入工作，并额外配置eclipse builder。这应该是一致的！此外，Eclipse中的错误解析应与maven构建的输出一致。

对于我的Java项目，这在开箱即用的情况下非常有效。Eclipse拾取了Maven配置，并进行CLEAN和BUILD，产生了完全应该有的结果。（尽管我看到Java Builder仍然活跃在项目的属性中。为什么？？）。但是，我无法使其与CDT一起正常工作。

当我禁用C++ Builder时，Eclipse只使用maven构建（这就是我想要的），但清除命令无法正确工作。此外，我还会被标记为编译器不认为是错误的错误。当然，这应该是一致的。

有没有针对这种情况的教程？

我没有找到关于这个主题的信息。我不确定自己是否正在走入一个错误的方向或者遗漏了最佳实践之类的东西？！

由于这是我的第一个s.o.问题，请随意给我反馈。我能提供的我会；-）

Eclipse不使用Maven构建。相反，它根据你的POM配置JDT。这是通过M2E（Maven到Eclipse）连接器完成的。如果你想让CDT也能如此工作，那么你需要一个相应的M2E连接器。我不知道是否已经存在这样的连接器，所以你需要编写一个Eclipse插件。请参阅http://wiki.eclipse.org/M2E/Extension_Development 了解更多详情。

当然，你还可以在POM的lifecycleMapping中使用“execute”而不是“ignore”。但这可能会导致构建非常缓慢，因为每次更改都会触发整个构建过程。并且仍然不能“神奇地”将Maven中的错误显示在你的文件中。
