Fatal error compiling: tools.jar not found:

When compiling a project in Eclipse, I get below error:

Fatal error compiling: tools.jar not found:

How is this caused and how can I solve it?

Solution

  • Goto Windows -> Preferences

    Java -> Installed JREs –> Execution Environment

    JavaSE1.x -> JDE 1.x

    If you don’t have the JDK in the Installed JRE, then

    Select the Installed JRE and Add the JDK installed path

    Let's try to configure your run configurations to clean install

    enter image description here

    Click on the small black arrow and then Run Configurations

    After, you just put clean install in your Maven goal, like this :

    And then, try to run your compilation, and we will see what happens... :)
