[jira] [Commented] (SUREFIRE-1376) "The forked VM terminated without properly saying goodbye" when running Surefire in a very deep project structure on Windows

Tibor Digana commented on SUREFIRE-1376:
----------------------------------------

[~gboue]
How did you compute 247?
In the MSDN you sent me {{"D:\some 256-character path string<NUL>"}} MAX_PATH_LENGTH_WINDOWS can be 259.
Basically it does not much matter because the number are very similar and prefix {{"\\\\?\\"}} does not harm the path.

> Error: Unable to access jarfile C:\Users\Guillaume\Desktop\surefire-longpath-test-with-windows\surefire-longpath-test-with-windows\surefire-longpath-test-with-windows\surefire-longpath-test-with-windows\surefire-longpath-test-with-windows\surefire-longpath-test-with-windows\target\surefire\surefirebooter2512478076549179739.jar

> The problem is that the path to the JAR file exceeds the maximum path length of 260 characters, and so it cannot be accessed.
> Prepending the path to the JAR file with {{&#92;&#92;?&#92;}}, [as documented on MSDN|https://msdn.microsoft.com/en-us/library/aa365247(VS.85).aspx#maxpath], makes the test run again correctly. I've attached a possible patch with this approach (SUREFIRE-1376-prefix.patch, that also handles UNC pathnames), but perhaps there is a better way to tackle this problem.
> In order to reproduce this, it is possible to create a project under lots of different subdirectories, something like:
> {noformat}
> └───surefire-longpath-test-with-windows
>     └───surefire-longpath-test-with-windows
>         └───surefire-longpath-test-with-windows
>             └───surefire-longpath-test-with-windows
>                 └───surefire-longpath-test-with-windows
>                     │   pom.xml
>                     │
>                     └───src
>                         └───test
>                             └───java
>                                 └───Test.java
> {noformat}
> As a side-note, this issue is behind the current Jenkins failures on [maven-plugins-ITs-m3.1.x-with-maven-plugin-jdk-1.8_windows|https://builds.apache.org/job/maven-plugins-ITs-m3.1.x-with-maven-plugin-jdk-1.8_windows/3702/] when running the ITs on the Assembly Plugin.
