问题描述
我下载了OpenJDK14的源代码并将其放在\home\yuanfang\jdk14中，并且在运行bash configure --disable-warnings-as-errors和make images之后，我成功地构建了OpenJDK14，而新构建的JDK在home\yuanfang\jdk14\build\linux-x86_64-server-release\jdk中。顺便说一句，我正在使用Ubuntu 20.04 LTS。
然后，我想使用CLion IDE调试OpenJDK14。我使用的是CLion 2020.2，请执行以下步骤：
- 打开CLion后，我选择从源代码创建新的CMake项目，然后选择目录
\home\yuanfang\jdk14，它是jdk项目的根目录。 - 我更改了运行/调试配置，使其看起来像这样：
- CLion自动创建一个
CMakeLists.txt，但是该文件无法正常工作，因此在进行谷歌搜索之后，我在https://github.com/ojdkbuild/ojdkbuild/blob/master/src/java-14-openjdk/CMakeLists.txt处找到了正确的CMakeLists.txt。然后，我使用正确的CMakeLists.txt改写旧的\home\yuanfang\jdk14。 - 我下载了整个存储库（即github.com/ojdkbuild/ojdkbuild），将其解压缩并放入
ojdkbuild-master中。 如下所示，CMake Error at CMakeLists.txt:19 (include): include Could not find load file: /home/yuanfang/jdk14/../../resources/cmake/ojdkbuild_common.cmake CMake Error at CMakeLists.txt:21 (include): include Could not find load file: /home/yuanfang/jdk14/../../resources/cmake/version.cmake CMake Error at CMakeLists.txt:93 (add_subdirectory): add_subdirectory given source "/home/yuanfang/jdk14/../../deps/rhino/scripting_tasks" which is not an existing directory.

- 我重新加载了CMake项目，但是发生了一些CMake错误（如下所示），为什么CLion无法找到那些文件？ javaI谷歌搜索，但找不到任何有效的@R_404_6280@案。有什么我可以做或参考的吗？预先感谢。

解决方法
- 步骤：查看此项目：https://github.com/ojdkbuild/ojdkbuild.git
- 步骤：将OpenJDK14的源代码放入ojdkbuild / src /
- 步骤：将reousrces目录和CMakelists.txt复制到OpenJDK14
- 步骤：重新编译openjdk并将项目导入到CLin
