I spose it must be some version problem but I don't know how to fix it. I created the project with STS on ubuntu using mostly default options

CodePudding user response：

It looks like you have java version problem. Can you check your java version which one you are using.

CodePudding user response：

You're using an outdated version of Boot (2.3.4, current is 2.7.0), which by default includes an outdated version of ASM that does not understand how to read Java 17 class files:

ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet

Update your Boot version to 2.7.0.
