Why does sbt say "No java installations installed" with $ JAVA_HOME set?
I have 2 sbt-android-scala projects. The first is one:
$ ls -al

drwxr-xr-x 4 alex staff 136 Dec 24 21:08 ..

The second has subprojects in it:

When I run sbt
in the first project, it compiles well, unlike the second:
$ sbt
No java installations was detected.
Please go to http://www.java.com/getjava/ and download
But
$ echo $JAVA_HOME
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

I only had one problem coming out of nowhere. When I executed java -version
, the following error was returned:
Error occurred during initialization of VM
Could not reserve enough space for object heap
It turned out that Eclipse was consuming all available memory and that I could not start another JVM. So I quit Eclipse and everything works fine.
