Java: 18.0.2 - /usr/bin/javac

What's your Gradle versions? You can find it inside the android/gradle/gradle-wrapper.properties file.

I believe you're on a old Gradle version which doesn't support Java 18. As an alternative, movign to JDK 11 should solve your issue.

Changing the distribution url in gradle-wrapper.properties to 7.6

That works! Thank you!

[moumen-engineer]

but which distribution of gradle (7.6-all.zip or 7.6-bin.zip . . .

[mattiarainieri]

What about eas build?

Changing the distribution url in gradle-wrapper.properties to 7.6

The right solution, thanks men

[tanmoy27112000]

SOLUTION:

go to android/gradle/wrapper/gradle-wrapper.properties

Find the distributionUrl variable and change the end path to gradle-7.6-all.zip

Changing the distribution url in gradle-wrapper.properties to 7.6

This doesn't seem to work anymore, as EAS just decides to use 7.5.1 no matter how many times gradle-wrapper.properties is changed.

If someone else is still in problems with this, the solution, in my case was to align my version of Gradle with the Java one. There is a compatibility matrix that explains which version of Gradle works with which version of Java. By aligning them, it worked on my env.

[YektaDev]

Can confirm. I started having this bug every now and then only after I upgraded the JDK version and the solution for me since I'm not planning on downgrading the JDK, was to instead delete the .gradle and build directories when this happens. Though it's strange that the behavior isn't deterministic. My guess is there are multiple versions of JDK being used by IDE/Gradle/etc.

Not Yet! Will update here once fix my side.

[ArnaudRm]

For people using Expo trying to build your app locally the "old way" with expo run:android or npx react-native run-android commands :

I came to understand that if you are in a managed Expo app, and you want to build your app locally , expo advises to use the "new way" of building locally with eas build(as documented here) The major issue for me here is that creating the local build this way with eas build will count in your build usage on expo.dev.

Moreover, ios and android folders are generated if you are in a managed workflow , meaning you cannot change the gradle version as advised in this comment for example because this setting will be overriden the next time you perform a build via eas build command

So, here's how I managed to run local builds with expo run:android or react-native run-android

The problem was the gradle version set by Expo was not compatible with the java runtime version installed on my machine

• I checked the version of gradle used by Expo, in android/gradle/wrapper/gradle-wrapper.properties
• Then I looked at the compatibility matrix between java and gradle
• Then, I switched the java version that was installed locally to use one compatible with gradle version used by Expo

BUG! exception in phase 'semantic analysis' in source unit 'BuildScript' Unsupported class file major version 65

Help me to overcome this ...

@NaveenG46 having same issue as you, funny no one has found a solution

[AndreiSager]

@NaveenG46 @Red3nzo I have the same problem. I am trying to use realm with expo on a bare workflow but none of the solutions I've found have worked.

I used the template given by expo. but I couldn't run it because I couldn't create a build.

I'm sorry to hear that you're having trouble with using Realm in an Expo bare workflow. Here are some steps you might find helpful:

1. Initialize the project: You can start a new project with the npx create-expo-app command. If you're using MongoDB Realm, you can use this command: expo init ReplaceWithNameOfYourAPP --template @realm/expo-template-ts.

2. Rename App.js to App.tsx: If you're using TypeScript, you'll need to rename your App.js file to App.tsx.

3. Create a tsconfig.json: You'll need a tsconfig.json file in your project root. You can create one with the touch tsconfig.json command.

4. Run the project: After setting up, you can run your project with yarn start or npm run start.

**Run the expo diagnosticscommand "inside your project" might also help provide further details of your error:

[GStar718]

i've found this to be useful.

1. Check the Java version used by Flutter: You can do this by running flutter doctor --verbose.

2. Update the Gradle version: You need to update the Gradle version specified in your android/gradle/wrapper/gradle-wrapper.properties file to be compatible with the Java version. For Java 17, you should use Gradle 7.3 or newer.

3. Change the Java version: If updating Gradle doesn't work, you can change the Java version used by your project. You can do this by adding or changing org.gradle.java.home in your gradle.properties file to point to the appropriate Java version.

[GStar718]

Always good to recheck your basic steps as well.

if your having trouble with using Realm in an Expo bare workflow. Here are some steps you might find helpful:

1. Initialize the project: You can start a new project with the npx create-expo-app command³. If you're using MongoDB Realm, you can use this command: expo init ReplaceWithNameOfYourAPP --template @realm/expo-template-ts.

4. Run the project: After setting up, you can run your project with yarn start or npm run start.

Remember, the bare workflow requires a good understanding of native development for both iOS and Android platforms. Developers should be familiar with Objective-C, Swift, Java, and Kotlin, in addition to JavaScript.
