Unsupported major.minor version 52.0 in 2.2.3 #38

Closed dbachelder closed 10 years ago

dbachelder commented 10 years ago

as mentioned in https://github.com/evant/gradle-retrolambda/issues/37

With JAVA8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home and JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home and JAVA7_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home

Even with 2.2.3 I get

me/tatarka/RetrolambdaPlugin : Unsupported major.minor version 52.0

unless I make JAVA_HOME=$JAVA8_HOME

OR set org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home

in gradle.properties

Also breaks AS integration unless I take the steps I mentioned in my first comment in #37

Could you run gradle clean assembleDebug --info and paste the output for java compilation which looks like:

Compiling with Java command line compiler '/opt/java/bin/javac'.
Starting process 'command '/opt/java/bin/javac''. Working directory: /home/evan/android/lambdatestProject/lambdaTestAndroid Command: /opt/java/bin/javac -source 1.8 -target 1.8 -d /home/evan/android/lambdatestProject/lambdaTestAndroid/build/retrolambda/debug -g -encoding UTF-8 -bootclasspath /opt/android-sdk/platforms/android-19/android.jar -bootclasspath /home/evan/android/lambdatestProject/lambdaTestAndroid/build/retrolambda/android-19/android.jar -classpath /opt/android-sdk/extras/android/m2repository/com/android/support/support-v4/13.0.0/support-v4-13.0.0.jar:/home/evan/android/lambdatestProject/lambdaTestAndroid/build/intermediates/exploded-aar/lambdatestProject/lambdaTestAndroidLib/unspecified/classes.jar:/opt/android-sdk/extras/android/m2repository/com/android/support/support-annotations/21.0.0-rc1/support-annotations-21.0.0-rc1.jar /home/evan/android/lambdatestProject/lambdaTestAndroid/src/main/java/me/tatarka/lambdatest/android/Other.java /home/evan/android/lambdatestProject/lambdaTestAndroid/src/main/java/me/tatarka/lambdatest/android/MainActivity.java /home/evan/android/lambdatestProject/lambdaTestAndroid/build/generated/source/r/debug/me/tatarka/lambdatest/android/R.java /home/evan/android/lambdatestProject/lambdaTestAndroid/build/generated/source/buildConfig/debug/me/tatarka/lambdatest/android/BuildConfig.java

and retrolambda (if it gets that far) which looks like:

Note: I'm not too worried about the AS integration. It makes sense that it wouldn't work if both AS and gradle is not running with java 8.

Bah.. I still had the old version of the plugin on one of my submodules! all set now. Sorry for the false alarm!
