Eclipse/Maven error: "No compiler is provided in this environment"

Go to Window → Preferences → Java → Installed JREs.

And see if there is an entry pointing to your JDK path, and if not, click on Edit button and put the path you configured your JAVA_HOME environment.

Screen_shot Add 'tools.jar' to installed JRE.

1. Eclipse -> window -> preference.
2. Select installed JREs -> Edit
3. Add External Jars
4. select tools.jar from java/JDKx.x/lib folder.
5. Click Finish

I tried all the things; the one that worked for me is:

1. Right click on Eclipse project and navigate to properties.
2. Click on Java Build Path and go to the Libraries tab.
3. Check which version of Java is added there; is it JRE or JDK?
4. If you are using Maven project and want to build a solution.
5. Select the JRE added their and click remove.
6. Click Add external class folder and add the JDK install by selecting from the system.
7. Click Apply and OK.
8. Restart Eclipse.
9. Build succeeded.

Go into Window > Preferences > Java > Installed JREs > and check your installed JREs. You should have an entry with a JDK there.
