Unable to open project

I am create new empty project, close this project, close Katalon Studio, open Katalon studio again and try to open this project. I am get “Unable to open project” error. Log file is attached

.log

Errors occurred during the build.

Error instantiating builder ‘org.eclipse.jdt.core.javabuilder’.

Plug-in org.eclipse.jdt.core was unable to load class org.eclipse.jdt.internal.core.builder.JavaBuilder.

An error occurred while automatically activating bundle org.eclipse.jdt.core (218).

Answer closed, it was very stupid situation: I am forget not installed Java. Maybe Katalon need notice user that he needs install last Java?

Your situation is not stupid at all, I believe. You do not have to install Java yourself for Katalon Studio, I believe. Because Katalon Studio bundles Java Runtime Environment which Katalon Studio depends upon. The following shows where the java binary on my Mac:

:bin$ pwd
/Applications/Katalon Studio.app/Contents/Eclipse/jre/Contents/Home/jre/bin
:bin$ ls -la java
-rwxrwxrwx@ 1 urayamakazuaki  admin  103632  6  3  2017 java

Why you experienced “Unable to open project”? How come installing Java yourself solved your problem? — I don’t see anything.

Please help me to resolve this issue ASAP.

hi @neeraj.srivastava, have you did this ?

@Joko_T_Susilo_Widodo
Thanks for replying dear but this also not working me. When I removed the files from the libs it showing me the build error and also getting an error as shown below:

hi @neeraj.srivastava how about if you create new project then copy your current project except libs to there, and try to open it

I have also tried that but seems not working for me. But I somehow resolve this issue by downloading new Katalon studio 6.1.5 and open my project.
Katalon developers should work on this type of issue.
