[尝试同时使用Firestore和Google Speech to Text库构建项目时，出现“重复类”错误。据我了解，这是由于两个库都引入了原型库。排除会产生运行时错误。如何解决重复问题？
这里是错误（串联，还有几百行）：
Duplicate class com.google.api.Advice found in modules jetified-proto-google-common-protos-1.17.0.jar (com.google.api.grpc:proto-google-common-protos:1.17.0) and jetified-protolite-well-known-types-17.0.0-runtime.jar (com.google.firebase:protolite-well-known-types:17.0.0)
Duplicate class com.google.api.Advice$1 found in modules jetified-proto-google-common-protos-1.17.0.jar (com.google.api.grpc:proto-google-common-protos:1.17.0) and jetified-protolite-well-known-types-17.0.0-runtime.jar (com.google.firebase:protolite-well-known-types:17.0.0)
Duplicate class com.google.api.Advice$Builder found in modules jetified-proto-google-common-protos-1.17.0.jar (com.google.api.grpc:proto-google-common-protos:1.17.0) and jetified-protolite-well-known-types-17.0.0-runtime.jar (com.google.firebase:protolite-well-known-types:17.0.0)
这是我的依赖项：
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.core:core-ktx:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'com.google.firebase:firebase-analytics:17.4.1'
implementation 'com.firebaseui:firebase-ui-auth:6.2.0'
implementation 'com.google.firebase:firebase-firestore:21.4.3'
// add these dependencies for the speech client
implementation 'io.grpc:grpc-okhttp:1.29.0'
implementation 'com.google.cloud:google-cloud-speech:1.23.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}
如果添加以下排除项，则编译有效，但随后出现Firestore的运行时错误：
configurations {
implementation.exclude module:'protolite-well-known-types'
implementation.exclude module:'protobuf-javalite'
}
这里是运行时Firestore错误：

我知道了。 Google语音文本Java库当前不支持Android，因此出现此错误。据我了解，protobuf-java（由Google Speech-to-Text使用）用于桌面解决方案，而protobuf-lite（由Firestore使用）用于移动解决方案。排除其中一个模块将破坏其各自的依存关系。
我的解决方法是创建自己的.jar，其中包含来自这两个类的类，包括项目中的.jar，然后从build.gradle中的依赖项中排除模块。这将确保我在项目中拥有正确的模块，而且还将确保仅获得类的一个副本。
我采取的步骤：
implementation('com.google.firebase:firebase-firestore:21.4.3') {
exclude module: 'protolite-well-known-types'
exclude module: 'protobuf-javalite'
exclude module: 'protobuf-java'
exclude module: 'protobuf-java-util'
}
implementation('com.google.cloud:google-cloud-speech:1.23.0') {
exclude module: 'protolite-well-known-types'
exclude module: 'protobuf-javalite'
exclude module: 'proto-google-common-protos'
exclude module: 'protobuf-java'
exclude module: 'protobuf-java-util'
}
编辑：
这无法完全正常工作。它允许项目进行编译并调用Firestore来运行，但是在尝试使用Google Speech-to-Text库进行任何方法调用时，都会产生运行时错误。
到目前为止，由于Android尚不支持Google Speech-to-Text，我认为无法将Firebase与Google Speech-to-Text库一起使用。
