Error occurred during initialization of boot layer java.lang.module.FindException executing Selenium tests using TestNG and Java 12 through Eclipse

Question

ErrorOccuredDuringInitializationofbootlayer I keep getting this error when I run my test:

Error occurred during initialization of boot layer java.lang

Answer 1

To avoid this error, do not add TestNG library in the project or src folder. Try adding it into the package. To do so , follow the below mentioned procedure.

Right click on the package, click Build Path->Configure Build Path, go to Libraries tab, select Classpath and click on Add Library to select TestNG.

This error message...

Error occurred during initialization of boot layer java.lang.module.FindException: 
Unable to derive module descriptor for C:\Users\Bonfire.eclipse\org.eclipse.platform_4.12.0_867647348_win32_win32_x86_64\plugins\com.beust.jcommander_1.72.0.jar 
Caused by: java.lang.IllegalArgumentException: com.beust.jcommander.1.72.0: Invalid module name: '1' is not a Java identifier

...implies that there was an issue with the java classpath.

As per the discussion Launch with java 11 fails: Error: Could not find or load main class with Caused by: java.lang.ClassNotFoundException: with there are some issues with some particular classpaths for java-11 and the launch fails if:

• The classpath contains a folder with spaces
• The classpath length is larger than 32767 characters.

Where as java-8 works fine.

Answer 3

Add TestNG Library to classpath in buildpath ( not to module path). It will work fine.
