Which settings.xml is used by jenkins slave?

I have a Jenkins master (running on a small Linux box) and a Jenkins slave (running on a "correct" XP machine).

I have configured both for all jibs to be run on the Windows XP slave.

Unfortunatly, each time a build is run on that slave, the build fails due to the following error :

ERROR: Ignore Problem expanding maven opts macros org.jenkinsci.plugins.tokenmacro.TokenMacroFound mavenVersion 3.0.3 from file jar:file:/E:/java-ext/apache-maven-3.0.3/lib/maven-core-3.0.3.jar!/META-INF/maven/org.apache.maven/maven-core/pom.propertiesParsing POMsERROR: Echec à la lecture des POMshudson.util.IOException2: remote file operation failed: C:\hudson\workspace\Autocat at hudson.remoting.Channel@ee5bc4:ndx-PC-winXP    at hudson.FilePath.act(FilePath.java:752)    at hudson.FilePath.act(FilePath.java:738)    at hudson.maven.MavenModuleSetBuild$RunnerImpl.parsePoms(MavenModuleSetBuild.java:817)    at hudson.maven.MavenModuleSetBuild$RunnerImpl.doRun(MavenModuleSetBuild.java:617)    at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:429)    at hudson.model.Run.run(Run.java:1374)    at hudson.maven.MavenModuleSetBuild.run(MavenModuleSetBuild.java:467)    at hudson.model.ResourceController.execute(ResourceController.java:88)    at hudson.model.Executor.run(Executor.java:145)Caused by: hudson.remoting.ProxyException: hudson.maven.MavenModuleSetBuild$MavenExecutionException: org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:[FATAL] Non-resolvable parent POM: Failure to find fr.perigee.java:java-parent:pom:0.0.6 in http://tinkerpop.com/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of tinkerpop has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM @ line 3, column 10

I know this error is due to the bad definition of repository containing those artifacts, because used repository is defined in settings.xml. So, my question is quite simple : how can I define which settings.xml file is used by a Jenkins slave ?
