Fatal error compiling: tools.jar not found: [closed]

Answer 1

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

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... :)

Answer 2

You need to put the right Java Build path for your project.

In Eclipse:

--> Right click the project name - Properties (keyboard shortcut: [Alt] + [Enter] )
--> Libraries
--> Change the JRE7 to JDK7.

And I think the problem will be solved that way ;)
