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

[~gboue]
I found the bug report [1].
My problem is that the command would have two class paths.
First is environment variable CLASSPATH or that one in Manifest Class-Path. 
That's done via 
{{File jarFile = createJar( classPath, providerThatHasMainMethod );}}
Second class path would be {{-cp}} or {{-classpath}}.
{{cli.createArg().setValue( "-cp" );}}
See the spec [2] I think {{-cp}} would replace Manifest Class-Path as well.
{{The JDK tools java, jdb, javac, and javah have a -classpath option which 
replaces the path or paths specified by the CLASSPATH environment variable 
while the tool runs.}}

> {noformat}
> 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 {{\\?\}}, [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
>                     │   pom.xml
>                     │
>                     └───src
>                         └───test
>                             └───java
>                                 └───Test.java
> {noformat}
