自从将Kotlin添加到我们的Android源代码后，我们的自动构建就出现了间歇性故障。大多数构建失败，而occaisonal构建，也许是1/10，也许会成功。在引入Kotlin之前没有发生错误，并且在我们的开发机器上本地构建时不会发生这些错误 - 仅在构建服务器上。
通过命令行构建（即gradlew assembleFlavour1Flavour2）时，我们收到以下错误：Plugin with id 'com.android.application' not found。但是，当我们从Android Studio（在构建服务器上构建相同的Jenkins slave）构建时，我们会得到一个稍微不同的错误：Plugin with id 'kotlin-android' not found。我更新了Android Studio（通过File > Settings > System Settings > Updates）和Kotlin（通过Android Studio > Tools > Kotlin > Configure Kotlin Plugin Updates）。
我们的根build.gradle如下：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.2.10'
repositories {
google()
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'io.fabric.tools:gradle:1.25.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我们的应用程序build.gradle app/build.gradle是（具有针对业务的特定部分编辑），如下所示：

为了完整性，使用--stacktrace：
从命令行获得完整输出FAILURE: Build failed with an exception.
* Where:

* What went wrong:
A problem occurred evaluating project ':app'.

* Try:
Run with --info or --debug option to get more log output.
* Exception is:

gradlew -v报告以下版本信息：
------------------------------------------------------------
Gradle 4.1
------------------------------------------------------------
Build time: 2017-08-07 14:38:48 UTC
Revision: 941559e020f6c357ebb08d5c67acdb858a3defc2
Groovy: 2.4.11
Ant: Apache Ant(TM) version 1.9.6 compiled on June 29 2015
JVM: 1.8.0_152 (Oracle Corporation 25.152-b16)
OS: Windows Server 2012 R2 6.3 x86
根据Android Studio中的SDK Manager，我们安装了以下SDK平台：Android API 27 (rev. 1)，Android 8.0 (Oreo) (rev. 2)，并安装了以下SDK工具：Android SDK Build-Tools，Android Emulator (27.0.2) （注意，该计算机是虚拟机，因此模拟器不起作用），Android SDK Platform-Tools (27.0.1)，Android SDK Tools (26.1.1)，Android Support Repository (47.0.0)，Google Repository (58)。
Android Studio版本为3.0，未构建AI-171.4443003，SDK工具26.1.1，平台版本API修订版1.“忽略更新”为空。
更新：尝试重新安装Kotilin插件并完全重新安装Android Studio，但都没有奏效。尝试在服务器上使用Kotilin创建一个新的默认Android项目，并且具有完全相同的问题。所以我认为它必须是服务器配置的问题。
我还发现我可以创建一个新的默认项目没有 Kotlin和它：在Android Studio中构建，但不通过CLI构建。< / p>
为什么会出现这些错误，我该怎么做才能解决它们？
答案 0 :(得分：0)
您缺少maven { url "https://maven.google.com" }。正确的应该是：
allprojects {
repositories {
google()
jcenter()
maven { url "https://maven.google.com" }
}
}
