Build fails with: invalid source release: 17

[reimager]

What is the proper way to resolve this error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':file_saver:compileDebugJavaWithJavac'.
> error: invalid source release: 17

I've just been going into ~/.pub-cache/hosted/pub.dev/file_saver-0.2.9/android/build.gradle

and changing:

    compileOptions {
        targetCompatibility JavaVersion.VERSION_17
        sourceCompatibility JavaVersion.VERSION_17
    }

to

    compileOptions {
        targetCompatibility JavaVersion.VERSION_1_8
        sourceCompatibility JavaVersion.VERSION_1_8
    }

but obviously thats not a real fix. (Also curious why do my projects have this issue and no one else seems to?)

[mrchenmo]

same question，I think the requirement of VERSION_17 is very unreasonable

[jamov]

I get this error even when building on machine with Java 17 (openjdk 17.0.9) installed. Changing the file ~/.pub-cache/hosted/pub.dev/file_saver-0.2.9/android/build.gradle according to the first message fixes the issue.

Hi there, was there any other resolution to this? For me the change above (targetCompatibility JavaVersion.VERSION_1_8 ) worked, but since is inside the pub cache, I'm assuming any pub operation might overwrite it, correct?

I also had to update my compileSdkVersion from flutter.compileSdkVersion to 34 to eliminate an warning/error on build (which still opens the app) and kotlin to latest (not really sure if connected but all happened at the same time)

I used the flutter run command to get rid of the error brought by version 17

[NeariX67]

I got it fixed by updating Android Studio.

Before doing anything, launch Android Studio and Click Help > About and take a note of the Runtime version. For me, it was a JDK 11 version. After updating to 2023.3.1 the same About page showed JDK 17 and the Android builds ran fine.

[adrianvintu]

Why are the PRs not merged?

Is there an alternative package?

[SzymonDziak]

Same error when running flutter build appbundle

`* What went wrong: Execution failed for task ':file_saver:compileReleaseJavaWithJavac'.

error: invalid source release: 17 `

Tried all the solutions above.

[hsoniwork]

The same error for indirect dependency for this package https://pub.dev/packages/to_csv

[SzymonDziak]

POTENTIAL FIX:

• The problem lies within the Android inner files, not the package itself.

Solution steps:

1. Visit the official website and download the latest version of Android Studio. link
2. Once installed, execute the command flutter build appbundle.
3. After following these steps, the issue should be resolved, and everything should function properly.

The potential fix does not work for CI/Github aAtions

[mellowcello77]

Do we have a fix yet guys? Thank you!

[NinoBass]

Is there any fix yet for CI/CD?

[adrianvintu]

You can use my fork

pubspec.yaml

  file_saver:
    git:
      url: https://github.com/adrianvintu/file_saver.git
      ref: VERSION_1_8

[OpenJarvisAI]

@incrediblezayed Can u please upgrade the lib? thanks

[OpenJarvisAI]

The correct way is remove these two lines;

android { namespace "com.incrediblezayed.file_saver" compileSdk 34

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
    minSdkVersion 19
}
// compileOptions {
//     targetCompatibility JavaVersion.VERSION_18
//     sourceCompatibility JavaVersion.VERSION_18
// }

}

[duongsang97]

android { namespace "com.incrediblezayed.file_saver" compileSdk 34

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
    minSdkVersion 19
}
// compileOptions {
//     targetCompatibility JavaVersion.VERSION_18

}
// compileOptions {

}

It's work for me

[hatemragab]

same here

[dvmatyun]

For me it helped to fork the repository and adjust content in following files (just place there same versions for java, kotlin and etc.): gradle-wrapper.properties build.gradle gradle.properties

[incrediblezayed]

I'm so sorry guys, if it is very urgent for everyone you guys can go ahead & use the package form the PR created by a contributor in issue #87 this will fix the issue, & further discussion of this issue will take place in issue #87 so follow up in that.

[ollyde]

It doesn't work with JavaVersion.VERSION_1_8 now...

Can we just stick with the Flutter recommended. It's annoying, this is the only package wasting my time.

[adrianvintu]

You may use this until we have an update from the developer

  file_saver:
    git:
      url: https://github.com/adrianvintu/file_saver.git
      ref: 0aae1be4df8d1c30f267e080d9bf6be9bd9a4147

yes, man I am facing same issue means i am using github CI/CD to autogenerate APk in github actions but some @plus_plugins like connectiivty_plus, share_plus are not working and you wll always get "invalid source release: 17" or similar ones .

[adrianvintu]

You can also use something like below, to force the VERSION_17 build

buildscript {
    ext.kotlin_version = '1.9.20'
    repositories {
        google()
        mavenCentral()
    }

    repositories {
