Same issue not able to compile project.....
I am using android API 24,

Error:unsupported class file version 52.0
Error:...while parsing com/checkout/CardValidator.class

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

Finally i found the solution

Change this code from checkoutkit. It is because of project is bound to JDK 7, but you have installed and using JDK 8, then all modules that were used in a project have to be compatible with JDK 7 and explicitly specified to use it, and if you are using Android SDK 23 and below that is the case. Otherwise, there will be an error because JDK 7 can't parse class files which were compiled by JDK 8 and have the version 52.

apply plugin: 'java'
dependencies {
testCompile 'junit:junit:4.+'
compile 'com.google.code.gson:gson:2.3.1'
testCompile 'com.github.tomakehurst:wiremock:1.57'
sourceCompatibility = 1.7
targetCompatibility = 1.7
}

Thank you for sharing your solution;
We updated the plugin to support JDK 8
