目前我正在学习 Flutter。

今天我遇到了这个错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

搜索了几个小时后我已经尝试过：

其他 gradle 版本其他launcher_icon 有或没有 settings_aar.gradle

发生此错误的同时，我在android 文件夹中还有一个名为settings_aar.gradle 的新文件。我不知道这是否与上面的错误有任何关系，还是其他原因。

上面错误中提到的colors.xml看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="ic_launcher_background">lib/assets/launcher/logo.png</color>
</resources>

错误之后，颤振继续构建我猜的包。前几个确实成功，直到发生第二个错误：

FAILURE: Build failed with an exception.

同样，我不知道这两个错误是否属于一起。

我正在尝试的实际颤振版本是1.17.5 flutter doctor -v 看起来像这样：

我知道这是一个很长的问题，但我想提供任何重要的东西。如果还有什么需要请告诉我。

非常感谢...

【参考方案1】：

好的。想通了。

将包flutter_launcher_icons更新为版本^0.7.5

删除了所有可绘制和 mipmap 文件夹中的所有图标。也删除了colors.xml。

在pubspec.yaml 中，用 png 替换 android 上的 jpg 启动器图标。

使用命令flutter pub run flutter_launcher_icons:main重新创建图标

清理项目并再次运行

现在编译/构建没有任何错误。

祝你好运！
