Java is portable because Java code can execute on all major platforms. When we compile Java source code into bytecode, we can use it in any platform supported by Java without modification, unlike other languages ​​that require compiling code for each platform.

When you try to complete your task, you get this error: “Not all requested modules can be enabled: [StandardModule:org.netbeans.modules.nbjavac jarFile in Java“.

This error is one of the most popular problems any programmer will make. So, why does it appear, and how can it be resolved? We’ll go over it with you.

Why Does The Error: Not all requested modules can be enabled: [StandardModule:org.netbeans.modules.nbjavac jarFile in Java Occur?

In Netbeans, when working with NetBeans and connected to the issue with NetBeans hints for Java not being display:

The file exists in C:\Users\...\AppData\Roaming\NetBeans\11.2\modules\org-netbeans-modules-nbjavac.jar.

It’s the sole module to be noted as missing.

I’m aware of the widespread issues with multiple modules which are not able to be activated because of a wrong JDK route. My route to JDK appears to be correct:

netbeans_jdkhome="D:\Program Files\Java\jdk1.8.0_231"

But you are still facing with the following error.

Not all requested modules can be enabled: [StandardModule:org.netbeans.modules.nbjavac jarFile: C:\Users…\AppData\Roaming\NetBeans\11.2\modules\org-netbeans-modules-nbjavac.jar]
