<p class="MsoNormal">jcl-over-slf4j is not a binding, it's an adapter. It implements the Apache Jakarta Commons Logging API, but instead of using the JCL to route log messages, it uses the installed SLF4j binding. But, it is true that the different SLF4j
jars be of compatible versions. I think the actual problem that you are running into is that you have specifically included a runtime binding jar, but you didn't mention whether you also explicitly include the slf4j-api jar as a compile time dependency.
If you didn't it will include the highest one explicitly included, which is the one specified by the ant.jar. <o:p></o:p></p>

<div>
<p class="MsoNormal">If I were you I would absolutely include the slf4j-api compile dependency, and probably the jcl-over-slf4j runtime dependency using the same version as your binding.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I’m running out of ideas– do I need to dig into the ant code & try and change the classpath (remove 1.7.10?) I don’t know if that would work if classes from 1.7.10 have already
been loaded – I’m hoping there’s a really simple solution I’ve just happened to overlook (like executing ant in a new process with a new classloader) but if anyone has a suggestion it would be appreciated.
