ErrorOccuredDuringInitializationofbootlayer I keep getting this error when I run my test:
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
How can I fix it?
回答1:
Add TestNG Library to classpath in buildpath ( not to module path). It will work fine.
回答2:
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.

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.
