Want to remove specific jars from Gradle fat jar

Question

My current build.gradle looks like below.

repositories {
    flatDir {
       dirs 'lib'
   }
   maven {      
    mavenCentral()
  }

 dependencies {    

  compile "commons-logging:commons-logging:1.0.4", 
          "org.apache.httpcomponents:httpclient:4.4",
          "org.apache.httpcomponents:httpcore:4.4",
          "com.fasterxml.jackson.core:jackson-annotations:2.5.1",             
          "joda-time:joda-time:2.7",


  compile files('../lib/abc.jar')
 }

 jar {
    manifest{
        attributes ("Version" : project.version, "${parent.manifestSectionName}")
        attributes ("Name" : project.name, "${parent.manifestSectionName}")     
    }

    from {
          configurations.runtime.filter( {! (it.name =~ /abc.*\.jar/ )}).collect {
             it.isDirectory() ? it : zipTree(it)
         }
    }
  }  

So as you can see I have removed abc.jar at runtime, but in the same way I want to remove few more jars. In short I want few jars inside of fat jar and needs to exclude few. So how can I achieve it?

The following example may help you. You need to add new configuration - it extends compile by default so it will be available during development but will not be included into resulting jar - as joda in the example below.

apply plugin: 'java'

repositories {
  mavenCentral()
}

configurations {
  lol
}

dependencies {    

  compile "commons-logging:commons-logging:1.0.4", 
          "org.apache.httpcomponents:httpclient:4.4",
          "org.apache.httpcomponents:httpcore:4.4",
          "com.fasterxml.jackson.core:jackson-annotations:2.5.1"

  lol "joda-time:joda-time:2.7"
}

jar {
  from {
    configurations.runtime.collect {
      it.isDirectory() ? it : zipTree(it)
    }
  }
}
