It will be a small post, just to help someone who is navigating in the web without hope =D.
Firstly, you don’t need to go to the Gradle web site and download from there. You can just use the apt-get from cwchien repository:
sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle
After that, you can try to see the version of your installed gradle:
gradle -version
If the gradle version be showed, is everything ok, but probably you gonna see this message below:
ERROR: JAVA_HOME is set to an invalid directory: /usr/lib/jvm/default-java Please set the JAVA_HOME variable in your environment to match the location of your Java installation.
Even if you try to define the JAVA_HOME as java installation default path on Ubuntu (e.g. /usr/lib/jvm/java-7-oracle), the gradle still doesn’t working. The only way that I found to fix it is renaming the java folder (java-7-oracle) to “default-java” where gradle expect to find the java in. You can do it executing this command:
sudo ln -s /usr/lib/jvm/java-7-oracle /usr/lib/jvm/default-javaAnd now, after gradle -version, you gonna see something like that:
Gradle 2.9
