标签： android gradle android-gradle build.gradle

在安装最新的android studio预览版后，我试图重新构建项目，但是在更新gradle版本时显示以下异常：

Optional[1]
Optional.empty

我的项目的成绩文件如下： build.gradle（Project）：

转到设置/ Gradle / Android Studio。 然后检查“启用嵌入式Maven存储库”。 而且你很好走。

对于我来说，它是通过添加以下内容修复的：

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8  // <= add this
        targetCompatibility JavaVersion.VERSION_1_8  // <= add this
    }
}

到android / app / build.gradle文件

问题来自于compileJjtree的配置方式，更具体地说是用于inputDirectory 19的值。该值设置为projectDir，最终将11传递给SourceTask.setSource2。默认情况下，Gradle中与SourceSet相关的任何配置都将被抓住。一切都递归在指定的源目录下。在大多数情况下，这是可以的，因为文件夹很深且位于项目的文件夹布局中。有时，使用旧版文件夹结构时，配置通常需要源目录更靠近项目根文件夹。在那种情况下，可能会包含更多文件，并且通常但并非总是如此，这些文件被指定为任务的输入。 Gradle将通过创建快照以供将来执行运行来兑现这些输入。在这种情况下，将发生两个问题。

Input snapshot will fail. Just like your current failure, the task will try to snapshot files that are unrelated to the task’s job. Those files could be system files or legitimately locked by another process.
Input snapshot will succeed but the task will never be up-to-date. A folder could be included in the snapshot that happens to be the output of another task that runs before (or after) your task. This will cause Gradle to wrongly detect a change for a task as some of the “input” are changed between runs. This will kind of happen in your case as the compileJjtree will snapshot the build folder which changes as more task are run.

据说，要解决您的问题，您将必须通过SourceTask的include和exclude方法来缩小compileJjtree中包含的文件数量。如果过滤模式变得过于复杂，则始终可以将inputDirectory移到更孤立的位置，并让Gradle遍历所有内容。

缩小compileJjtree任务的范围可以解决此问题。

读取...

  

ModuleVersionNotFoundException：找不到com.android.tools.build:aapt2:3.2.0-alpha18-4804415。

对于4.10 com.android.tools.build:gradle，您可能需要Gradle> = 3.3.0

（或3.2.0-alpha18的至少一个更高版本）。

这可以在gradle-wrapper.properties中进行更改：

distributionUrl = https\://services.gradle.org/distributions/gradle-4.4-all.zip

存在此问题，因为我的网络无法连接到Maven存储库。更改我的网络设置可以完成工作

使用gradle文件同步项目对我有用。enter image description here
