Removing a jar in sourceSets.main.runtimeClasspath

I have this in my gradle:

sourceSets {
    main {
        compileClasspath += configurations.provided
        runtimeClasspath += configurations.provided
    }
    test {
        compileClasspath += configurations.provided
        runtimeClasspath += configurations.provided
    }
}

When I print the runtimeClasspath in this code:

task runTopology(type: JavaExec) {
    classpath = sourceSets.main.runtimeClasspath

    sourceSets.main.runtimeClasspath.each { println it }

I get something like:

...
/home/steven/.gradle/caches/modules-2/files-2.1/com.lmax/disruptor/3.3.2/8db3df28d7e4ad2526be59b54a1cbd9c9e982a7a/disruptor-3.3.2.jar
/home/steven/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-api/2.1/588c32c91544d80cc706447aa2b8037230114931/log4j-api-2.1.jar

/home/steven/.gradle/caches/modules-2/files-2.1/org.slf4j/log4j-over-slf4j/1.6.6/170e8f7395753ebbe6710bb862a84689db1f128b/log4j-over-slf4j-1.6.6.jar
...

Is it possible to exclude the line below in sourceSets.main.runtimeClasspath?

/home/steven/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.1/fe9d0925aeee68b743e9ea4b68ca9190a2a411a/log4j-slf4j-impl-2.1.jar

I do not want to include it in the runtimeClasspath as it crashes with another class in the classpath.

You can use FileCollection.filter() to filter by file name.
The following will exclude log4j-slf4j-impl-2.1.jar from runtimeClasspath : 

sourceSets {
    main {
        compileClasspath += configurations.provided
        runtimeClasspath += configurations.provided
        runtimeClasspath = runtimeClasspath.filter { File file ->
            file.name ==~ "log4j-slf4j-impl-2.1.jar" ? null : file
        }
    }
    test {
        compileClasspath += configurations.provided
        runtimeClasspath += configurations.provided
        runtimeClasspath = runtimeClasspath.filter { File file ->
            file.name ==~ "log4j-slf4j-impl-2.1.jar" ? null : file
        }
    }
}
