Unity3d 中的构建错误：无法确定任务 ':launcher:compileDebugJavaWithJavac' 的依赖关系。 ':launcher:debugRuntimeClasspath'

Question

在我的 Unity3d 项目中添加 Firebase Cloud 功能后出现此错误。

有人遇到同样的问题吗？

我们已经尝试过“flutter doctor --android-licenses”，就像在 https://github.com/flutter/flutter/issues/30573

到目前为止没有任何效果。

以下是完整的错误消息。

Answer 1

经过几天的折磨（不是几个小时），我们最终可以建造。但以下是我们发现的一个令人惊讶的事实。在 Unity3d 中，三个 google 包 firebase、google-signin 和 googleMobileAds 存在无法解决的依赖问题，因此我们无法成功构建。所以在所有组合试验结束时，我们决定从我们的项目中删除 googleMobileAds，然后我们终于可以成功地为“Android”构建。

我们在没有任何代码的情况下尝试了一个空项目。结果是一样的。失败的。上面提到的包在空场景中使用空的 unitypackage 构建失败。

我会给你每个包的详细版本。

Unity3d (Unity 2020.3.19f1)

firebase_unity_sdk.8.6.2

google-signin-plugin-1.0.4

GoogleMobileAds-v6.1.2

我遇到了类似的问题，原因是使用 gradle 版本 32.0.0。

请查看此链接表单 unity issuetracker：

• https://issuetracker.unity3d.com/issues/android-android-build-fails-when-targeting-sdk-31-and-using-build-tools-31-dot-0-0

所以我通过卸载构建工具 32.0.0 并改用 30.0.2 来解决它（来自 sdk 管理器）。
