[GROOVY-6023] ERROR: JAVA_HOME is set to an invalid directory

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.1.1
• Component/s: command line processing

Description

The problem takes place when JAVA_HOME contains "/../". For example:

set THIS_DIR=%~dp0.

:: Resolve platform root dir
set MB_HOME=%THIS_DIR%\..

:: Resolve java home.
set JAVA_HOME=%MB_HOME%\jdk-1.6.0_25-win64

:: Resolve groovy home.
set GROOVY_HOME=%MB_HOME%\groovy-2.1.1

call "%GROOVY_HOME%\bin\groovy.bat" "%THIS_DIR%\mb.groovy" %*

In this case we have JAVA_HOME=C:\some\path\scripts\.\..\jdk-1.6.0_25-win64.

In the subsequently called startGroovy.bat the lines:

@rem Validate JAVA_HOME
%COMMAND_COM% /C DIR "%JAVA_HOME%" 2>&1 | %FIND_EXE% /I /C "%JAVA_HOME%" >nul
if not errorlevel 1 goto valid_JAVA_HOME_DIR

give non-zero errorlevel, because the output of DIR command doesn't contain "C:\some\path\scripts\.\..\jdk-1.6.0_25-win64", it actually contains "C:\some\path\jdk-1.6.0_25-win64".

The solution of the problem can be code like:

if exists "%JAVA_HOME%\bin\java.exe" ...
