I thought on a solution. In Portuguese it is a "gambiarra". Maybe the term in English is kludge.
I could to build two profiles. A to run on specific server-group1 and another to run on other server-group2.
In server-group1 I put all slaves without thread files.
In server-group2 I put only one slave with thread files.
Now, I need found how to do this in pom.xml.
The correct way to exclude a file:
<packagingExcludes> inside configuration maven-war-plugin
