环境

仅记录编译遇到的两个问题

编译

git clone git@github.com:apache/flink.git
cd flink
git checkout -b xxx release-1.11.2-rc1
mvn clean package -DskipTests -e

问题

1. 依赖包下载失败，需要重新获取

   

   [ERROR] Failed to execute goal on project flink-azure-fs-hadoop: Could not resolve dependencies for project org.apache.flink:flink-azure-fs-hadoop:jar:1.11.2: Failure to find io.reactivex:rxjava:jar:1.3.8 in http://192.168.0.139:8081/repository/maven-public/ was cached in the local repository, resolution will not be reattempted until the update interval of nexus_public has elapsed or updates are forced -> [Help 1]
   org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project flink-azure-fs-hadoop: Could not resolve dependencies for project org.apache.flink:flink-azure-fs-hadoop:jar:1.11.2: Failure to find io.reactivex:rxjava:jar:1.3.8 in http://192.168.0.139:8081/repository/maven-public/ was cached in the local repository, resolution will not be reattempted until the update interval of nexus_public has elapsed or updates are forced
   ```

   flink-azure-fs-hadoop 模块的依赖 jar 包 io.reactivex:rxjava:jar:1.3.8 未下载完全，因为本地有缓存，编译时不会重新拉取，手动删除如下图的目录，重新编译下载即可。

   

2. 库中缺少依赖包，需手动下载

   

   [ERROR] Failed to execute goal on project flink-avro-confluent-registry: Could not resolve dependencies for project org.apache.flink:flink-avro-confluent-registry:jar:1.11.2: Could not find artifact io.confluent:kafka-schema-registry-client:jar:4.1.0 in nexus_public (http://192.168.0.139:8081/repository/maven-public/) -> [Help 1]
   org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project flink-avro-confluent-registry: Could not resolve dependencies for project org.apache.flink:flink-avro-confluent-registry:jar:1.11.2: Could not find artifact io.confluent:kafka-schema-registry-client:jar:4.1.0 in nexus_public (http://192.168.0.139:8081/repository/maven-public/)

下载 Jar 后重新编译，直接通过 IDEA 导入
