eclipse开发创建一个工程异常信息

今天在开发eclipse创建一个插件，通过测试环境结果报如下错误

org.eclipse.core.internal.resources.ResourceException: Invalid project description.
 at org.eclipse.core.internal.resources.Project.checkDescription(Project.java:124)
 at org.eclipse.core.internal.resources.Project.create(Project.java:227)
 at org.netliving.studio.project.wizards.StudioProjectWizard.createProject(StudioProjectWizard.java:186)
 at org.netliving.studio.project.wizards.StudioProjectWizard.createNewProject(StudioProjectWizard.java:150)
 at org.netliving.studio.project.wizards.StudioProjectWizard.createStudioProject(StudioProjectWizard.java:106)
 at org.netliving.studio.project.wizards.StudioProjectWizard$1.run(StudioProjectWizard.java:74)
 at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:113)

--------------------------------------------------------------------------------------------------------------------------

有如下方式原因造成

1) In the "default" location. This means that the project directory is a direct child directory of the workspace directory (aka the platform instance location), and the project directory name matches the project name.

2) Outside the default location, in a directory that is neither a parent or child of the platform instance location. In this case the directory name does not need to match the project name.

 

后来在创建工程的时候又出现如此错误

org.eclipse.core.internal.resources.ResourceException: Resource '/y' does not exist.

然后google终于查询处了结果，并解决掉了

The resource APIs are a bit tricky here.  When you create a new project,
you should specify the project location as null if you want it to go in
the default location -- i.e., <workspace root> / <project name>. 

Only use IProjectDescription#setLocation[URI]() to set a non-null
location if it *won't* live in that default location, otherwise you'll
get the "overlapping location" error.
规则阿。。。。
