java - error: Source option 6 is no longer supported. Use 7 or later. When decompiling MCP

Question

Im trying to decompile the MCP v1.8.8 on mac but when I run the decompile.sh file I get this error:

error: Source option 6 is no longer supported. Use 7 or later.
error: Target option 6 is no longer supported. Use 7 or later.

If i look in eclipse > Client the folder is empty so i cant do anything
