The Genuine solution for this problem for windows OS is: BY Setting up the path variable

Easy 5 steps would be:

STEP 0: Goto Window button and click Edit System Environment

STEP 1: Goto Advanced>>Environment variables>>Edit PATH

STEP 2: Change path value as::

   **(1):** the jdk installed folder:- C:\Program Files\Java\jdk-12.0.1\bin

   **(2):** copy the location of the path variable which is default i.e.: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Git\cmd   

    **(3):** Merge both of them and paste/update into variable value as:- C:\Program Files\Java\jdk-12.0.1\bin**;**%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Git\cmd

STEP 3: Open cmd by:- ctrl+r

STEP 4: Check for the current java version that you have installed for compliance to the machine by:- java -version (if it doesn't works, try:- jshell -version)

STEP 5: After getting the version launch eclipse IDE and create new java project and set the location of installed jdk as: C:\Program Files\Java\jdk-11.0.2

Thereafter, your java application would run efficiently.

Why this problem arises: When we install multiple jdk and runs eclipse, our machine as well as eclipse ide need the synchronization of the java version installed. So, the solution is to change the path variable on the system and set ide java version as well.

I came here looking for solution. The problem in my case was that src/test/java was specified as a source dependency in build path, but the folder did not exist. NPE went away after I removed the dependency.

Guess it would be a good idea to check whether Build path entries are missing in any of the projects and resolve them to get rid of this error.

Comments
  • please point the exact error from problems tab. if not visible enable it from window->show view ->problems.
  • the Problem window is empty ... there are no problems
  • This helped me solve my issue. In changing the name of my main project (altering the classpath), a dependent project was no longer associated with my project, so to resolve the issue I had to go to the properties, and add back the project to the Java Build Path.
  • I removed all libraries, saved and added them again. worked! thanks
