I got this error when I tried to run my Android program.

Error:Execution failed for task ':app:transformClassesWithPreJackPackagedLibrariesForDebug'. java.lang.AssertionError: java.util.zip.ZipException: duplicate entry: jayce/org/hamcrest/BaseDescription.jayce

here is my build.gradle

android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
    applicationId "com.surgical.decision"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    jackOptions {
        enabled true
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile files('libs/simple-xml-2.7.1.jar')
compile files('libs/log4j-1.2.17.jar')
compile files('libs/pddl4j-3.5.0.jar')
}

I have to enable jackOptions because there are a lot of function that I wrote in Java 8.
