[Solved] Java path error - Unable to install Forge source

[HinaK]

I run into problems when trying to install the Forge source as per the wiki guide. The script seems to be unable to locate my java installation. I have entered the correct paths to the PATH variable. I am using Windows XP. I have tried using both the latest and latest stable versions of Forge.

 

This is the console output when running the batch from a freshly extracted archive:

javac: Files\Java\jdk1.6.0_41\bin\javac is an invalid flag

Usage: javac <options> <source files>

Notice how it aborts with the error javac: Files\Java\jdk1.6.0_41\bin\javac is an invalid flag. My Java SDK is installed in C:\Program Files\Java\jdk1.6.0_41\. This suggests that the installer does not account for the space in the path.

 

As I already stated, I have included the paths in the PATH environment variable. I tried adding quotation marks to the path, but the installer seems to run the same regardless of what values PATH has. Running echo %PATH% in a command prompt produces the correct paths, so that should not be the problem.

Solved.

 

Go to forge\fml\fml.py and look at line 263:

        cmd_compile = '"%s" -Xlint:-options -deprecation -g -source 1.6 -target 1.6 -classpath "{classpath}" -sourcepath "{sourcepath}" -d "{outpath}" "{target}"' % self.cmdjavac

 

Remove the quotation marks from "%s" and you're done.

 

The weird thing about this is that it implies the installer does account for paths with spaces, but for some reason that didn't stop it from breaking for me. So normally this shouldn't even be a problem.
