Question

我需要为我的flutter项目释放一个签名的apk，但是“ flutter build apk --release”命令失败。

“ flutter build apk --debug”命令运行正常。我已经使用“ Flutter Doctor”检查了设置，一切似乎都很好。我曾尝试用飘动的清洁来清洁项目，但这没有帮助。

“ flutter build apk --debug -v”返回的错误是：

Gradle build failed to produce an Android package.

根据Android SDK文档，您可以根据sdkmanager的位置使用以下命令：--licenses选项上的文档似乎丢失了。

yes | sdkmanager --licenses

GNU / Linux发行版：

yes | ~/Android/Sdk/tools/bin/sdkmanager --licenses

macOS ：

导出JAVA_HOME = / Applications / Android \

Studio.app/Contents/jre/jdk/Contents/Home
yes | ~/Library/Android/sdk/tools/bin/sdkmanager --licenses

Windows：

%ANDROID_HOME%/tools/bin/sdkmanager --licenses

同时运行Flutter Clean

Answer 2

如果您正确地跟踪了Signing the app的此链接（如果您想将其上传到游戏商店），那么以下命令应该可以正常工作：

flutter build apk --release

如果上述方法不起作用，请尝试使用：

flutter build apk  // this command default creates the release apk, but don't know if you can upload it to play store

Answer 3

错误是由于密钥库的密码无效所致。修复后，编译正确。

flutter build apk-当flutter build apk发行失败-调试正常
