### 4、问题总结

#### **Q1：dependencies at io.confluent:kafka-avro-serializer:jar**

ERROR] Failed to execute goal on project hudi-utilities_2.12: Could not resolve dependencies for project org.apache.hudi:hudi-utilities_2.12:jar:0.10.1: Failed to collect dependencies at io.confluent:kafka-avro-serializer:jar:5.3.4: Failed to read artifact descriptor for io.confluent:kafka-avro-serializer:jar:5.3.4: Could not transfer artifact io.confluent:kafka-avro-serializer:pom:5.3.4 from/to maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories: [nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public/, default, releases)] -> [Help 1]

解决：将原来的mirror也打开，阿里仓库没有

Starting from versions 0.11, Hudi no longer requires spark-avro to be specified using --packages

#### **Q2：The goal you specified requires a project to execute but there is no POM in this directory (/root). Please verify you invoked Maven from the correct directory**

解决：切换到有pom的文件夹下才能执行
