错误:多个库的包名称为 com.google.android.gms.license

问题描述

当我尝试运行命令 ionic cordova build android 时出现如上标题所示的错误.然后我尝试删除其中一个 gms，当我再次构建时，删除它再次出现.如何解决这个问题?

When I try to run the command ionic cordova build android out error as title above. Then I try to remove one of the gms, when I build again the deleted it appears again. how to solve this?.

这是我的 build.gradle 的依赖项:

Here is my dependencies of my build.gradle :

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    debugCompile(project(path: "CordovaLib", configuration: "debug"))
    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    compile "com.google.android.gms:play-services-auth:+" // i remove this
    compile "com.google.android.gms:play-services-identity:+"
    compile "com.facebook.android:facebook-android-sdk:4.+"
    // SUB-PROJECT DEPENDENCIES END
}

推荐答案

我最近遇到了这个问题，对我来说问题是由于某种原因，android project.properties 文件是为 com.xml 生成的不同版本的.google.android.gms，例如:

I've faced this issue quite recently and the problem for me was that for some reason the android project.properties file was generated with different versions for the com.google.android.gms, as such:

target=android-26
android.library.reference.1=CordovaLib
cordova.system.library.1=com.android.support:support-v4:24.1.1+
cordova.system.library.2=com.google.android.gms:play-services-auth:+
cordova.system.library.3=com.google.android.gms:play-services-identity:+
cordova.system.library.4=com.google.android.gms:play-services-location:11.+

这使得 library.2 和 library.3 需要一个版本，而 library.4 需要一个更具体的版本，从而导致在编译期间重复库引用.

This makes the library.2 and library.3 require one version while the library.4 requires a more specific version, thus causing the duplicate library reference during compiling.

虽然我不认为这应该是最终解决方案，但添加特定库对我有用.因此:

While I don't think this should be the final solution, adding the specific library worked for me. As such:

target=android-26
android.library.reference.1=CordovaLib
cordova.system.library.1=com.android.support:support-v4:24.1.1+
cordova.system.library.2=com.google.android.gms:play-services-auth:11.+
cordova.system.library.3=com.google.android.gms:play-services-identity:11.+
cordova.system.library.4=com.google.android.gms:play-services-location:11.+
