Gradle 3.0.0-beta1构建问题

时间：2017-08-10 06:30:36

标签： android android-studio android-gradle build.gradle gradlew

我刚刚将gradle版本更新为

classpath 'com.android.tools.build:gradle:3.0.0-beta1'

将android studio更新为3.0-beta1后，我的gradle-wrapper为：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip

问题是当我想要Gradle-sync项目时，我正面临这个奇怪的问题：

我检查过所有内容，看起来都很好，有人可以帮忙吗？

Build -> Clean project，然后是

Build -> Rebuild project

答案 1 :(得分：3)

根据官方 link，这是已知问题。

  

已知问题 ：如果您有一个现有的Android Studio项目，那就是＆＃39; s   使用Android版插件3.0.0的alpha版本（例如3.0.0-alpha9），   迁移到Android插件时，您可能会收到以下错误   3.0.0-beta1和sync your project： Gradle项目刷新失败。

     

解决方案 ：选择构建＆gt;解决此问题从菜单中清除项目   bar - 您需要为每个项目仅执行一次此操作。您   然后，您可以点击同步项目，将项目文件与Gradle同步   从菜单栏。

答案 2 :(得分：2)

尝试此选项：

  1. 保持Gradle Sync错误，并清理项目
  2. 重建项目
  3. 现在同步Gradle

    4. 注意： 我也做了

      

    无效并重新启动

    在尝试之前

    它帮助了我，希望它也能帮到你。

答案 3 :(得分：0)

3.0.0中存在一些已知错误，这个问题就是其中之一，实际上android studio正在为Linux操作系统集成Unix文件系统（Berkeley Fast File System）并且它处于测试阶段....请将你的工作室降级到2.3.3现在稳定版。

答案 4 :(得分：0)

我在更新 beta1 后遇到了同样的问题。 尝试在SDK Manager中将构建工具更新到最新版本 - ＆gt; SDK工具。然后将google maven添加到 root build.gradle ，如下所示：

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
    }
}

这适用于我的情况

答案 5 :(得分：0)

我尝试在Linux Mint 18.1上升级到3.0.0-beta1时遇到了同样的问题。以上都没有帮助：既不干净 - ＆gt;重建 - ＆gt;同步，也无效和无效重新开始。但Sanat建议降级到2.3.3有助于
