从依赖项中排除模块后，多个 Gradle 重复类

Question

Gradle文件包含以下依赖项

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation 'javax.xml.bind:jaxb-api:2.2.12'
implementation 'javax.xml.stream:stax-api:1.0-2'
implementation 'com.fasterxml:aalto-xml:1.0.0'
implementation group: 'xerces', name: 'xercesImpl', version: '2.8.0'
implementation 'com.google.android.gms:play-services-auth:15.0.1'
implementation 'pub.devrel:easypermissions:0.3.0'
implementation('com.google.api-client:google-api-client-android:1.23.0') {
exclude group: 'org.apache.httpcomponents', module: 'commons-codec'
}
implementation('com.google.apis:google-api-services-gmail:v1-rev83-1.23.0') {
exclude group: 'org.apache.httpcomponents'
}
implementation 'com.google.oauth-client:google-oauth-client-jetty:1.23.0'
}

在其他几个多类错误中，commons-codec在依赖树中有以下用法

+--- com.google.api-client:google-api-client-android:1.23.0
|    +--- com.google.api-client:google-api-client:1.23.0
|    |    +--- com.google.oauth-client:google-oauth-client:1.23.0
|    |    |    +--- com.google.http-client:google-http-client:1.23.0
|    |    |    |    +--- com.google.code.findbugs:jsr305:1.3.9
|    |    |    |    --- org.apache.httpcomponents:httpclient:4.0.1
|    |    |    |         +--- org.apache.httpcomponents:httpcore:4.0.1
|    |    |    |         +--- commons-logging:commons-logging:1.1.1
|    |    |    |         --- commons-codec:commons-codec:1.3
--- commons-codec:commons-codec:{strictly 1.3} -> 1.3 (c)

图 问题可能与传递依赖项有关，但据我通过对依赖项树的分析了解，只有org.apache.httpcomponents将其用作库，但是，由于某种原因我无法掌握，Gradle 构建文件中的排除声明没有按预期工作。

请注意，docx4j-6.1.1-SNAPSHOT-shaded.jar是添加到 libs 文件夹的 jar。不确定为什么这些 jar 文件没有显示在依赖关系树中。

Answer 1

因此，通过排除传递依赖项的所有实例，它起作用了

configurations {
all*.exclude group: 'commons-codec', module: 'commons-codec'
}

这种方法有什么缺点吗？通过这样做，google-api-client-android模块中是否包含的所有方法都使用commons-codec使用docx4j-6.1.1-SNAPSHOT-shaded.jar依赖项的方法？这两个不能使用commons-codec模块的不同构建版本吗？
