Hello,

In the JaCoCo plugin I would like to use ASM 3.3.1 but the ASM 2.2.3 is loaded for some reason (maybe Jenkins uses it?). How could I tell Jenkins to use a newer ASM when the plugin's classes are loaded?

Thank you!

Br, Ogi

You can switch the classloader delegation mode (it is a config parameter of the maven plugin)

Kohsuke write something around this a while back http://kohsuke.org/2012/03/03/potd-package-renamed-asm/

But using those packages might interfere with JaCoCo too much.

Can you help me how to do the switch? Is there any wiki our mailing list thread about it?

Thank you,

Ogi

I guess you just want: <pluginFirstClassLoader>true</pluginFirstClassLoader>

Yes, this is what I recommend --- use the package renamed version tied
to the major ASM version.

But this only works if you are the user of ASM, and not if you need to
bundle a library that uses ASM. For this situation, I think Jenkins
supports class masking that lets you ignore specific packages from the
dependencies and from the core.

Hmm. Yes, looks like the plugin loads the ASM 3.3.1, but still I have the same problem. This is about JaCoCo plugin.

The shade plugin helped me in this:

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.3.1</version>
