Answer 1

进入设置/摇篮/ Android的工作室。然后勾选“启用嵌入式Maven仓库”。你是好去。

Answer 2

在我的情况下，固定加入：

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

到Android /应用程序/文件的build.gradle

Answer 3

为具有因为我的网络无法连接到Maven仓库这一问题。更改我的网络设置做了工作

Answer 4

这个问题源于compileJjtree是如何配置的更具体用于inputDirectory 19.值设置为PROJECTDIR这最终被通过11至SourceTask.setSource 2.默认情况下的值，在摇篮任何SourceSet相关的配置会抓住一切递归下源目录指定。在大多数情况下，该文件夹是深刻的和孤立的项目的文件夹的布局，这是好的。一旦在一段时间，更常见的与传统的文件夹结构，配置需要源目录以更接近所述项目根文件夹。在这些情况下，多了很多文件可以包含并经常但并非总是如此，这些文件被指定为输入到任务。摇篮会为未来的执行运行快照纪念那些输入。在这种情况下，会出现两个问题。

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.

那有人说，解决您的问题，你将不得不缩小文件中包含的compileJjtree通过包括数量和排除SourceTask方法。如果过滤模式变得太复杂，你可以随时移动inputDirectory地方更加孤立，并让glob的摇篮一切。

减少compileJjtree任务的范围内解决这个问题。

Answer 5

它读取...

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

您可能需要为4.10 com.android.tools.build:gradle摇篮> = 3.3.0

（或至少是更高版本，比你有什么，现在，对于3.2.0-alpha18）。

这可以在gradle-wrapper.properties改变：

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

Answer 6

同步项目的gradle与文件工作了me.
