我有一个多项目结构，其中包含数十个同级项目以及不同的子项目，如下所示：
master/
proja/
|-- projaEAR
|-- projaJAR
projb/
|-- projb
|-- projbhelper
etc/
最终，我想在settings.gradle中动态生成项目。但是，我在Windows上遇到了麻烦。引发此错误：
java.io.IOException: The filename, directory name, or volume label syntax is incorrect
使用我当前的gradle安装（v2.2.1），错误来自GfFileUtils.java：
Caused by: java.io.IOException: The filename, directory name, or volume label syntax is incorrect
at org.gradle.util.GFileUtils.canonicalise(GFileUtils.java:222)
这是我的设置：
C:\TEMP\gradle_test\master>dir /b /ad /s ..
C:\TEMP\gradle_test\foo
C:\TEMP\gradle_test\master
C:\TEMP\gradle_test\foo\foo
C:\TEMP\gradle_test\foo\proja

如果我使用较新的gradle（v5.2.1），问题可能出在其他地方：
C:\TEMP\gradle_test\master>c:\apps\gradle-5.2.1\bin\gradle -s projects
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':foo:foo'.

相同的简单设置在Linux上也可以正常工作
