在使用 gradle 和 Java 7 构建的 android 项目中，将 targetSdkVersion 从 19 更改为 21 时，在运行 robolectric 测试时会引发以下异常：
构建.gradle：
apply plugin: 'com.android.application'
apply plugin: 'robolectric'
android {
compileSdkVersion 21
buildToolsVersion '21.0.2'
defaultConfig {
minSdkVersion 9
targetSdkVersion 21
versionCode 6
versionName '2.0.0'
}
...
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v4:21.0.+'
compile 'org.roboguice:roboguice:2.0'
compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
compile 'com.github.rtyley:roboguice-sherlock:1.5'

compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'com.squareup:fest-android:1.0.+'
testCompile 'org.mockito:mockito-all:+'
testCompile 'junit:junit:4.11'
testCompile 'org.robolectric:robolectric:2.3+'

androidTestCompile 'org.mockito:mockito-all:+'
androidTestCompile 'junit:junit:4.11'
androidTestCompile 'org.robolectric:robolectric:2.3+'
}

当 targetSdkVersion 设置为 19 时不会抛出此异常。
