Java 25 asm issue

[uhoefel]

Affected version

<= 3.15.1

Bug description

Using the latest maven-plugin-plugin 3.15.1 with classes from Java 25 fails due to asm being too old:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-plugin-plugin:3.15.1:descriptor (default-descriptor) on project myproject.plugin: Execution default-descriptor of goal org.apache.maven.plugins:maven-
plugin-plugin:3.15.1:descriptor failed: Unsupported class file major version 69 -> [Help 1]

This probably should be fixed by #948

I guess using the new ClassFile API is not an option due to the supported java version being 8?

[uhoefel]

The failure of #948 looks transient to me, com.vladsch.flexmark:flexmark-ext-tables:0.62.2 is e.g. in maven central and seems fine.

@uhoefel I had this same problem with maven plugin tool 3.15.1 in my project and it seems that forcing org.ow2.asm:asm* versions to 9.8 in the parent POM fixed the build.

              <version>9.8</version>
            </dependency>
          </dependencies>
        </plugin>
         <!-- More content -->
       </plugins>
     </pluginManagement>
    </build>
  </project>

So I think maven-plugin-tools DOES NEED to upgrade the org.ow2.asm:asm* dependencies at least to 9.8 in order to properly support Java 25

#979 looks like it has been upgraded already

@slawekjaranowski I saw milestone 3.15.2 has 100% of the issues closed. Is there any estimation of date for a 3.15.2 release?

Thanks in advance
