我正试图在这个存储库https://github.com/khpeek/pdf-parser中跟踪这篇博客文章，https://github.com/khpeek/pdf-parser。运行./gradlew build之后，该项目具有以下结构：

BUILD FAILED in 810ms
4 actionable tasks: 1 executed, 3 up-to-date我尝试在dependencies中添加以下行到build.gradle，
compile group: 'io.grpc', name: 'protoc-gen-grpc-java', version: '1.14.0'但这也导致了同样的错误。有什么办法来修复Gradle的构建吗？

io.grpc.*在grpc-api (大多数其他grpc依赖项将依赖于此)中。io.grpc.stub.*在grpc-stub。io.grpc.protobuf.*在grpc-protobuf。javax.annotation.Generated可以在Tomcat的annotations-api中找到。
因此，您需要添加(如grpc-java自述中提到的)：
implementation "io.grpc:grpc-protobuf:1.14.0"
implementation "io.grpc:grpc-stub:1.14.0"
compileOnly "org.apache.tomcat:annotations-api:6.0.53"gRPC v1.14.0已经很老了；您应该升级到一个较新的版本以供实际使用。要实际运行，您可能还需要implementation 'io.grpc:grpc-netty-shaded:1.34.1'。
