How to fix InvalidModuleDescriptorException<\/h2>\n

The exception java.lang.module.InvalidModuleDescriptorException is caused by an unnamed package not allowed in a module.<\/p>\n

Error<\/h3>\n
Error occurred during initialization of boot layer\r\njava.lang.module.FindException: Error reading module: \r\nF:\\eclipse-workspace\\Sample\\bin\r\nCaused by: java.lang.module.InvalidModuleDescriptorException: \r\nSampleClass.class found in top-level directory (unnamed package not allowed \r\nin module)<\/pre>\n

\"InvalidModuleDescriptorException\"<\/h3>\n
Fixes<\/h2>\n
Check the JDK version of the project. InvalidModuleDescriptorException is a runtime exception usually thrown when reading module descriptor.<\/p>\n
# Refactor the code<\/h3>\n
If we want the project to be as Java module, then we need to refactor the code. The above error occurs when Java classes are created right under the default src<\/strong> default package folder. The unnamed package is not allowed in the module with the latest JDK.<\/p>\n
We must declare a named package because this compilation unit is associated to the named module.The name of the module can be found in module-info.java<\/strong> during the project creation phase. To avoid this kind of exception, move all the classes that are in the default package to some named packages.<\/p>\n
Create a Package.<\/strong><\/p>\n
Steps to create a new package in Eclipse IDE<\/p>\n
https:\/\/www.testingdocs.com\/questions\/how-to-create-a-package-in-eclipse-ide\/<\/a><\/p>\n
Refactor the code to move the classes in unnamed packages to named ones.<\/p>\n

\"Java<\/p>\n
 <\/p>\n
# Module descriptor file<\/h3>\n
If you still see the error:<\/p>\n
Check the module descriptor file module-info.java . <\/strong>This file contains the metadata for the module dependencies, packages exports, etc.<\/p>\n
# Not a Java Module<\/h3>\n
If we don’t want the project to be a Java module then simply delete the module-info.java<\/strong> module descriptor file to fix this error.<\/p>\n
