I got **UnsupportedClassVersionError** when CircleCI runs gradle dependencies command.

I believe this is because Android 24 requires Java 1.8 ---

Hi, I am having the same issue since updating to the 2.2.0 version of the gradle plugin. I am not targetting the 24 version of Android, so I don’t know what could cause this issue. Do you have any ideas? Thanks! ---

The 2.2.0 version of the gradle plugin likely requires Java 1.8 as well. ---

Wow, do you have in hand some kind of guide on how to do this? Thanks! ---

Another question, and why does it work on my local machine without having to switch on Java 1.8 support. At this time, enabling Jack&Jill can be pretty difficult on my project ---

Fixed this issue by changing to use Java 1.8 on circle server using circle.yml: `machine: environment: ANDROID\_HOME: /usr/local/android-sdk-linux ADB\_INSTALL\_TIMEOUT: “20" TERM: “dumb” \_JAVA\_OPTIONS: “-Xms1024m -Xmx2048m" GRADLE\_OPTS: '-Dorg.gradle.jvmargs=”-Xmx2048m -XX:+HeapDumpOnOutOfMemoryError”' java: version: openjdk8 ` ---
