Unity error: Exception: Gradle install not valid

Question

我在 Unity 上制作了一个简单的基于文本的 Android 应用程序。当我尝试构建它来制作应用程序包时，出现了以下错误。如果有熟悉这些错误的人，你能给我一些解决问题的建议吗？

错误 1

"Details of the errors"

当 Unity 在应用程序构建过程中处理以下这 3 个部分时，总是会出现错误。

1，Hidden/VideoDecode - Flip_NV12_To_RGB1：剥离顶点程序

2, Hidden/Compositing -Mix_RGBA_To_RGBA: 剥离顶点程序

3，Hidden/VideoDecodeAndroid - RGBASplitExternal_To_RGBA：剥离顶点...

"About Unity platform"

我的Unity版本：2019.2.9f1和2019.2.13f1（遇到错误我更新了）

我用的

Android SDK(28.0.3),NDK(android-ndk-r16b) 和openJDK(1.8.0_152)都是原来安装的Unity 版本。

"Gradle install with Unity(recomemded)" 项已经检查过。

我在第一次构建项目时选择了LWRP模板。

Answer 1

我遇到了类似的问题。
对我来说，来自 https://answers.unity.com/questions/1534863/gradle-install-not-valid.html 的答案有效：

if you go to editor>Preferences External Tools tab there is a check box for Gradle Install with Unity. Make sure this check box is checked

Answer 2

检查您的 gradle 路径。它应该是包含 lib/gradle-launcher-*.jar

的文件夹

就我而言，它只是将 UnityEditor 设置中的 gradle 路径从 /usr/local/Cellar/gradle/6.7.1 更改为 /usr/local/Cellar/gradle/6.7.1/libexec

UnityEditor 错误应该更详细地说明此类错误配置。

// UnityEditor.Android.GradleWrapper
internal static string GetBaseCommand(int jvmHeapSize)
{
    string gradleLaunchJarPath = AndroidGradleRoot.GetGradleLaunchJarPath(AndroidGradleRoot.GetInstance().GetRootDirectory());
    bool flag = string.IsNullOrEmpty(gradleLaunchJarPath);
    if (flag)
    {
        throw new Exception("Gradle install not valid");
    }
    return string.Format("-classpath \"{0}\" org.gradle.launcher.GradleMain \"-Dorg.gradle.jvmargs=-Xmx{1}m\"", gradleLaunchJarPath, jvmHeapSize);
}

// UnityEditor.Android.AndroidGradleRoot
internal static string GetGradleLaunchJarPath(string directory)
{
    string path = Paths.Combine(new string[]
    {
        directory,
        "lib"
    });
    string[] array = AndroidFileLocator.Find(Path.Combine(path, "gradle-launcher-*.jar"));
    bool flag = array.Length == 1;
    string result;
    if (flag)
    {
        result = array[0];
    }
    else
    {
        result = null;
    }
    return result;
}
