mvn.bat always exits 0 on Windows 2000 and higher
-------------------------------------------------
Key: MNG-2127
URL: http://jira.codehaus.org/browse/MNG-2127
Project: Maven 2
Type: Bug
Components: Command Line
Versions: 2.0, 2.0.1, 2.0.2
Environment: I'm on Windows 2003 Server, but this will affect any OS for which
the %OS% environment variable is Windows_NT, including Windows XP and Windows
2000.
Reporter: Dan Fabulich
Priority: Blocker
Write the following ant script and run it on Windows 2000 or higher: <project
default="main"><target name="main"><exec executable="mvn.bat"
failonerror="true" /></target></project>
This will run "mvn" with no arguments, which will always fail. But the ant
script will claim "build successful", because the exit value of mvn.bat was 0.
It is absolutely critical that this work correctly, or else I can't integrate
Maven into any other automated system.
This is happening because mvn.bat is improperly abusing local scoping. On line
130 of mvn.bat, we execute maven, but we don't do anything with its exit
value... we just always goto end. The fix for this is to add a line 131 that
says "if errorlevel 1 goto error", which will behave correctly.
(I marked this as having a test case because I've included a test ant script,
but technically this isn't a JUnit test case, so it may be an inappropriate use
of the "testcase included" marker.)
