eclipse - eclipse中的预定义变量是什么？

Question

使用eclipse，我知道如何在启动配置中使用变量。我还知道存在一组预定义变量，例如ECLIPSE_HOME或WORKSPACE_LOC。

我不知道这些预定义变量的广泛列表(即:变量名称和值)。有这样的资源吗？

我在eclipse帮助文档中找到了一个有关路径变量的很好的例子:workbench user guide-concepts-ant & external tools假设您的Eclipse工作区目录为:c:\eclipse\workspace，并且您有两个项目MyProject1和MyProject2。第一个项目MyProject1位于工作空间目录中，第二个项目MyProject2位于工作空间目录之外的c:\projects\MyProject2。让我们看一下如果选择了资源/MyProject2/MyFolder/MyFile.txt时，在运行外部工具时如何扩展下面的变量示例。

    ${workspace_loc} ~~> c:\eclipse\workspace
    ${workspace_loc:/MyProject1/MyFile.txt} ~~> c:\eclipse\workspace\MyProject\MyFile.txt
    ${workspace_loc:/MyProject2/MyFile.txt} ~~> c:\projects\MyProject2\MyFile.txt
    ${project_loc} ~~> c:\projects\MyProject2
    ${project_loc:/MyProject1/MyFile.txt} ~~> c:\eclipse\workspace\MyProject
    ${container_loc} ~~> c:\projects\MyProject2\MyFolder
    ${resource_loc} ~~> c:\projects\MyProject2\MyFile.txt
    ${project_path} ~~> /MyProject2
    ${container_path} ~~> /MyProject2/MyFolder
    ${resource_path} ~~> /MyProject2/MyFolder/MyFile.txt
    ${project_name} ~~> MyProject2
    ${container_name} ~~> MyFolder
    ${resource_name} ~~> MyFile.txt
    ${build_type} ~~> none
