others-How to solve module java.base does not 'opens java.lang' to unnamed module?
1. Purpose
In this post, I would demonstrate how to solve the following exception when running spring cloud eureka server in intellij IDEA:
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.5.2.RELEASE:run (default-cli) on project service-discovery: An exception occurred while running. null: InvocationTargetException: Cannot load configuration class: org.springframework.cloud.bootstrap.config.PropertySourceBootstrapConfiguration: ExceptionInInitializerError: Unable to load cache item: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @505e2a79 -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

2. The solution
2.1 The detailed error
I want to start an eureka server in IntelliJ IDEA, but I got this error:

2.4 Debug the error
Check the java version:
➜ chapter03 -- hello-cloud git:(master) ✗ java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
2.5 The solution
run the following command in parent module:
mvn install
Then re-run the module:
mvn spring-boot:run
But double-clicking the run to run the spring-boot plugin in the idea still reports an error:
2.6 The reason of the error
Idea use jdk 1.6 to start spring applicaiton, just as the logs show:
/Library/Java/JavaVirtualMachines/temurin-16.jdk/Contents/Home/bin/java ...
Then I check:
➜ chapter03 -- hello-cloud git:(master) ✗ /Library/Java/JavaVirtualMachines/temurin-16.jdk/Contents/Home/bin/java --version
openjdk 16.0.2 2021-07-20
OpenJDK Runtime Environment Temurin-16.0.2+7 (build 16.0.2+7)
OpenJDK 64-Bit Server VM Temurin-16.0.2+7 (build 16.0.2+7, mixed mode, sharing)
➜ chapter03 -- hello-cloud git:(master) ✗
It’s jdk1.6,not 1.8, that is the problem.
Change project sdk to 1.8:
Then click ‘spring-boot:run’ to run again:

It works!
