Your build path is pointing to the wrong JRE directory/folder. You need to select the JRE folder which is present inside the JDK

Steps to change

  1. Go to eclipse- click on windows(Last second option)
  2. Click on Preferences- Search for Installed JREs
  3. click on add -> select standard VM- click next
  4. Under JRE Home - click directory -< Navigate to the location in your system where Java is downloaded

for eg C:\Program Files\Java\jdk1.8.0_241\jre 5. Select Finish-> check the folder selected-> apply -> apply and close

Clean your project and compile it. It should work fine :)

I faced that error after update my java version from 1.8.0_201 to 1.8.0_221. In the new folder the tools.jar was missing. I found tools.jar file on previous version under "C:\Program Files\Java\jre1.8.0_201\lib" directory(Assuming java is installed under C:\Program Files). I just copied the file and pasted on "C:\Program Files\Java\jre1.8.0_221\lib". The tools.jar file also can be found on "C:\Program Files\Java\jdk1.8.0_161\lib"(version that I installed) directory. It solved my problems. Not quite sure as it is the perfect solution but it works every time. Hopefully same technique would work for other OS too.

Tried all that was mentioned in the above solutions but didn't work. Finally, after scratching up my head for hours, I could do it with below actions:

windows > preferences > installed jres > click edit on the selected jre/jdk > add external jar > add in tools.jar

Hope this helps you save a lot of time. Cheers!

If you're getting this in eclipse make sure that Eclipse is pointing to a JDK and Not a JRE.

In Eclipse navigate to Window->Preferences->Java->Installed JRES- Add... Standard VM and point Directory... to a JDK. You'll obviously need to install a JDK if you have not done so.

I think you need to point JAVA_HOME to a JDK not just a JRE. The JRE is the java runtime environment while the JDK is for development and will contain the compiler and libs required.
