Posted April 12, 201411 yr After learning some java i was ready to start modding Minecraft so i downloaded everything i needed and everything was going perfect until... i went to command prompt to run gradlew.bat setupDecompWorkspace--refresh-dependencies where i got this error. **************************** Powered By MCP: http://mcp.ocean-labs.de/ Searge, ProfMobius, Fesh0r, R4wk, ZeuX, IngisKahn MCP Data version : unknown **************************** Download http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.7.2-10.12.0.1024/forge-1.7.2-10.12.0.1024-userdev.jar FAILURE: Build failed with an exception. * What went wrong: The setupDecompWorkspace will only work with Java 7! This is fixed in ForgeGradle 1.2 * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. I am currently using java8 and i understand the error came from there but do i really need to downgrade the java version? Or is there another way?
April 12, 201411 yr aup, you really need to downgrade. I did the same thing only to realise the same thing today. Because Java 8 is only just out, nothing has had time to update (like mods when a new version of Minecraft comes out). Make sure you have both JRE and JDK 7 and you set your path environment variable to point to it (there are a million guides of this, just search "JDK path environment variable" and repeat for JRE). Happy coding! I have no idea what I'm doing.
