无法从此列表中找到要调用的方法 maven():

Question

我目前正在尝试为Android模拟(然后构建(和Ionic App(带Angular(。我觉得有必要先说我不是Android开发人员，这是我第一次必须设置环境，所以我为任何"明显"的错误或错过的步骤道歉。

我一直无法克服此错误(运行ionic cordova emulate android --debug --consolelogs后出现(：

BUILD FAILED

Error: /path/to/app/platforms/android/gradlew: Command failed with exit code 1 Error output:

A problem occurred evaluating root project 'android'.

public abstract org.gradle.api.artifacts.repositories.MavenArtifactRepository org.gradle.api.artifacts.dsl.RepositoryHandler#maven(org.gradle.api.Action)

当我尝试构建项目或同步 Gradle 时，我在 Android Studio 中收到类似的消息：

Could not find which method maven() to invoke from this list:

我的build.gradle文件中失败的行如下所示：

buildscript {
repositories {
maven ()        < HERE
jcenter()
google ()
}
// Switch the Android Gradle plugin version requirement depending on the

}
}

对于上下文，我有：

下载了Android Studio，JDK和SDK工具，以及(在尝试故障排除时(通过自制软件安装了Gradle和Maven。

将以下路径添加到我的.bash_profile(并确认文件路径包含他们所说的内容，以及匹配的版本(：

export ANDROID_HOME=$HOME/Library/Android/sdk`
export JAVA_HOME=$(/usr/libexec/java_home)
export JRE_HOME=$JAVA_HOME/jre

export PATH=$PATH:$M2_HOME/bin
export PATH=$PATH:/opt/gradle/gradle-4.7/bin

Answer 1

之后

apply plugin: 'com.android.application'

您应该添加以下内容：

repositories {
mavenCentral()
maven {
url "https://repository-achartengine.forge.cloudbees.com/snapshot/"
} //  some dependency like this.
}

如果您有具有身份验证的 maven，则可以使用：

repositories {
mavenCentral()
maven {
credentials {
username xxx
password xxx
}
url    'http://mymaven/xxxx/repositories/releases/'
}
}

这是重要的顺序。

注意：您需要在构建脚本之外定义存储库。构建脚本配置块仅设置构建脚本类路径的存储库和依赖项，而不设置应用程序的存储库和依赖项。看到这里
