"ionic capacitor run android" fails with latest @capacitor packages

donniehale-awh · April 15, 2022, 2:53pm

When I run ionic capacitor run android with the more recent @capacitor package versions in “package.json”, I get an error:

[capacitor]         D:\Src\GeneralRV\mobile\builds\20220414\android>"C:\Other Programs\Java\jdk-18/bin/java.exe" "-Xmx64m" "-Xms64m"   "-Dorg.gradle.appname=gradlew" -classpath "D:\Src\GeneralRV\mobile\builds\20220414\android\\gradle\wrapper\gradle-wrapper.jar" org.gradle.wrapper.GradleWrapperMain "assembleDebug"

[capacitor]         General error during conversion: Unsupported class file major version 62

Below is more information that I think is significant. Output of “ionic info”:

Ionic:

   Ionic CLI       : 6.19.0 (C:\Other Programs\nodejs\node_modules\@ionic\cli)
   Ionic Framework : @ionic/react 6.0.1

Capacitor:

   Capacitor CLI      : 3.4.3
   @capacitor/android : 3.4.3
   @capacitor/core    : 3.4.3
   @capacitor/ios     : 3.4.3

Utility:

   cordova-res : 0.15.4
   native-run  : 1.5.0

System:

   NodeJS : v16.14.2 (C:\Other Programs\nodejs\node.exe)
   npm    : 8.5.0
   OS     : Windows 10

Here are the relevant lines in package.json:

    "@capacitor/android": "3.4.3",
    "@capacitor/app": "1.1.1",
    "@capacitor/core": "3.4.3",
    "@capacitor/haptics": "1.1.4",
    "@capacitor/ios": "3.4.3",
    "@capacitor/keyboard": "1.2.2",
    "@capacitor/status-bar": "1.0.8",

IMPORTANT (I think): If I change those lines to the following and run npm install, and change nothing else, the command works:

    "@capacitor/android": "3.3.3",
    "@capacitor/app": "1.0.7",
    "@capacitor/core": "3.3.3",
    "@capacitor/haptics": "1.1.3",
    "@capacitor/ios": "3.3.4",
    "@capacitor/keyboard": "1.2.0",
    "@capacitor/status-bar": "1.0.6",

By “change nothing else”, I mean: same shell, same folder, same command, etc. For me, this is reproducible. And it seems to be totally out of my control.

The full output of the error when I run with the --verbose argument is:

Any direction for me on how to get past this? I know that for now I can stick with the earlier package versions, but at some point I’ll have to update.

Thanks.

If you change your $JAVA_HOME variable to be the OpenJDK version bundled with Android Studio and not JDK 18 installed on your PC, does it build? While you can use other Java installations, I’m not sure if Android Studio works nicely with the newest JDK yet

donniehale-awh · April 18, 2022, 3:48pm

I got other errors about too old a version of Java when I had JAVA_HOME set to a different version of it. Not sure if it was specifically the Android Studio-bundled version, though. I’ll try that.

donniehale-awh · April 18, 2022, 3:56pm

That seems to have worked. Specifically,

# Powershell on Windows 10
$Env:JAVA_HOME="C:\Program Files\Android\Android Studio\jre"

It might be helpful if this document specifically called out the right/best setting for JAVA_HOME, given that the document has instructions for setting a number of other environment variables.

Thanks.
