[SOLVED][1.7.2 #1013] fault in setting up DecompWorkspace

[Paul17041993]

basically, after having a bunch of faults in my modding I decided to try updating forge from #998 to a more recent version (#1013), only to find this fault in gradle which I cant get around, attempted ~10 times, ultimately trying on a 100% clean setup (yes I deleted .gradle in my user folder too) with the same result each time...

 

ultimate error seems to be;

Caused by: java.io.IOException: Cannot run program "javac" (in directory "D:\Users\Paul - Admin\Minecraft stuff\Forge Modding\Forge1.7.2\build\tmp\recompForge\sources"): CreateProcess error=2, The system cannot find the file specified

at org.gradle.process.internal.ExecHandleRunner.run(ExecHandleRunner.java:69)

Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified

 

t'isnt it meant to point to the JDK directory...?  I tried updating the JDK to u51 as it was on u45 before, though nothing else has had any issues with it...

SOLUTION; you need to add the JDK to your PATH variable, be sure to reboot your computer after too (windows)

SOLUTION FOR 2ND PROBLEM; see below for the .classpath fix if you need it, fixes net and cpw libraries being missing

[Paul17041993]

ok somewhat as I expected it was due to the Path variable not being present, but it not being needed until now confuses me, was there a change to the back-end between #998 and #1011 that needs javac now...?

[Paul17041993]

not intending to multi-post but its either that or make a new topic...

 

a second fault now is that both the minecraft and forge sources are missing from the .classpath folder on creation.

*slowclap*

I haven't yet determined the correct paths for the correct files to inject into the file, a few have changed (in name etc) since #998...

[Paul17041993]

ok would have edited the previous post but that seems partially broken atm...

 

if you add the missing classpathentry below you should be able to use #1013 and compile without it complaining that net and cpw are missing;

<classpathentry kind="lib" path="C:/Users/*USERNAME*/.gradle/caches/minecraft/net/minecraftforge/forge/1.7.2-10.12.0.1013/forgeBin-1.7.2-10.12.0.1013.jar"/>

 

replace *USERNAME* with your user, C with whatever drive your users is in (usually C:, but some people like me have it in D:), then you should *hopefully* not have any issues.
