Jacoco Task taking forever

The Jacoco Task sometimes takes forever to run. Sometimes, it runs immediately and other times, it just gets stuck doing the same task over and over again. You can see the gradle task in the picture below. The gradle file (slimmed down to important info) looks like:
build.gradle Project Level
```
buildscript {
dependencies {
classpath('com.dicedmelon.gradle:jacoco-android:0.1.3') { exclude group: 'org.codehaus.groovy', module: 'groovy-all' }
}
}
```

build.gradle App Level
```gradle
apply plugin: 'jacoco-android'

android {
testOptions {
animationsDisabled true
unitTests {
includeAndroidResources = true
}
unitTests.all {
jvmArgs '-noverify'
jacoco {
includeNoLocationClasses = true
}
}
}
}

jacocoAndroidUnitTestReport {
csv.enabled true
html.enabled false
xml.enabled false
}
```
