    Error building with JDK 13 - Solution

    Just in case anyone is having issues with the error "General error during semantic analysis: Unsupported class file major version 57" this can be caused by having JDK 13 installed since UE4 is using gradle 5.

    You can either downgrade JDK to 12 or edit this file
    Window: C:\Program Files\Epic Games\UE_4.25\Engine\Build\Android\Java\gradle\gradle\wrapper\gradle-wrapper.properties
    macOS: /Users/Shared/Epic Games/UE_4.25/Engine/Build/Android/Java/gradle/gradle/wrapper/gradle-wrapper.properties

    Change

    Code:
    distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip
    to

    Code:
    distributionUrl=https\://services.gradle.org/distributions/gradle-6.0-all.zip
    That will allow the build to happen at least
Working...
