Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_151 contains a valid JDK installation

Question

Even though I manually configured JDK project structure file/Project structure it still shows this error FAILURE: Build failed with an exception.

`What went wrong:

Answer 1

My issue was two-fold:

1. I had the JRE installed, but not the JDK.
2. I did not have a JAVA_HOME environment variable set.

Note: I am using Fedora Linux.

To resolve the first issue, I followed these instructions

To resolve the second, I merely added the following line to my ~/.bashrc file:

export JAVA_HOME=/usr/lib/jvm/java/

I had to restart my IDE and terminals to ensure the change to the ~/.bashrc took affect.
