Problem When I tried to add JDK 14 to my eclipse, the following error was shown Target is not a JDK root. System library was not found. Target is not a JDK root. System library was not found. My downloaded JDK folder was named as jdk-14 Solution I simply renamed my folder from jdk-14 to jdk-14.0 and it worked. The jdk 14 was successfully added to the Eclipse. Conclusion I t seems that sometimes Eclipse is not able to locate the jdk folder, renaming the folder refreshes the cache of Eclipse and then respective folder is located by Eclipse.
