Gradle does not find tools.jar

Question

I am using javadoc doclets with gradle, so I need to use the package tools.jar, which is in the lib folder from the jdk (1.6.0_26 in my case).

The point is that gradle does not take it automatically, so I was adding that tools package to my libs folder, and then adding it to dependencies.gradle .

Now I want to take it directly from my JDK home into my dependencies.gradle. Is there a way to do that? I have tried the next in my dependencies.gradle:

compile files("${System.properties['java.home']}/lib/tools.jar")

But it does not find it while compiling.

I had this problem when I was trying to run commands through CLI.

It was a problem with system looking at the JRE folder i.e. D:\Program Files\Java\jre8\bin. If we look in there, there is no Tools.jar, hence the error.

You need to find where the JDK is, in my case: D:\Program Files\Java\jdk1.8.0_11, and if you look in the lib directory, you will see Tools.jar.

What I did I created a new environment variable JAVA_HOME:

And then you need to edit your PATH variable to include JAVA_HOME, i.e. %JAVA_HOME%/bin;

Re-open command prompt and should run.
