kafka-rest：怎么愉快的build？

愉快的build该项目吧

git clone https://github.com/confluentinc/kafka-rest
mvn clean install -Dmaven.test.skip=true

出先如下类似错误：

[ERROR] Failed to execute goal on project kafka-rest: Could not resolve dependencies for project io.confluent:kafka-rest:jar:3.1.-SNAPSHOT: The following artifacts could not be resolved: io.confluent:rest-utils:jar:3.1.-SNAPSHOT, org.apache.kafka:kafka_2.:jar:0.10.1.0-SNAPSHOT, io.confluent:kafka-avro-serializer:jar:3.1.-SNAPSHOT, io.confluent:kafka-json-serializer:jar:3.1.-SNAPSHOT, io.confluent:rest-utils-test:jar:3.1.-SNAPSHOT, org.apache.kafka:kafka_2.:jar:test:0.10.1.0-SNAPSHOT, org.apache.kafka:kafka-clients:jar:test:0.10.1.0-SNAPSHOT, io.confluent:kafka-schema-registry:jar:3.1.-SNAPSHOT: Could not find artifact io.confluent:rest-utils:jar:3.1.-SNAPSHOT in confluent (http://packages.confluent.io/maven/) -> [Help 1]

翻了一下该项目wiki：

https://github.com/confluentinc/kafka-rest/wiki/FAQ 描述如下：

When I try to compile I get an error about a missing SNAPSHOT dependency.

The error looks something like this:

[ERROR] Failed to execute goal on project kafka-rest: Could not resolve dependencies for project io.confluent:kafka-rest:jar:3.1.0-SNAPSHOT: The following artifacts could not be resolved: io.confluent:rest-utils:jar:3.1.0-SNAPSHOT, org.apache.kafka:kafka_2.11:jar:0.10.1.0-SNAPSHOT, io.confluent:kafka-avro-serializer:jar:3.1.0-SNAPSHOT, io.confluent:kafka-json-serializer:jar:3.1.0-SNAPSHOT, io.confluent:rest-utils-test:jar:3.1.0-SNAPSHOT, org.apache.kafka:kafka_2.11:jar:test:0.10.1.0-SNAPSHOT, org.apache.kafka:kafka-clients:jar:test:0.10.1.0-SNAPSHOT, io.confluent:kafka-schema-registry:jar:3.1.0-SNAPSHOT: Could not find artifact io.confluent:rest-utils:jar:3.1.0-SNAPSHOT in confluent (http://packages.confluent.io/maven/) -> [Help 1]

During development of new versions of the REST Proxy we sometimes use a SNAPSHOT versions of dependencies in order to build and test against new features. If you want to build a development version, you may need to build and install these dependencies to your local Maven repository in order to build the connector:

• Kafka - clone https://github.com/apache/kafka/ and build with ./gradlew installAll
• rest-utils - clone https://github.com/confluentinc/rest-utils and build with mvn clean install
• schema-registry - clone https://github.com/confluentinc/schema-registry and build with mvn clean install

按照上述说法，一通搞，还是不行

翻了一下该项目Issues 描述如下：

@ewencp thanks for the summary, that finally also worked for me. I used the following steps (a bit in more detail) to build it. 
Actually our company network (proxy and maven repo) was a problem since could either resolve dependencies or run the integration tests. Therefore, I had to skip the tests.

git clone --branch 1.1. https://github.com/apache/kafka.git
gradle wrapper
./gradlew installAll

git clone https://github.com/confluentinc/common.git
git checkout origin/4.1.x
mvn clean install -Dmaven.test.skip=true

git clone https://github.com/confluentinc/rest-utils.git
git checkout origin/4.1.x
mvn clean install -Dmaven.test.skip=true

git clone https://github.com/confluentinc/schema-registry.git
git checkout origin/4.1.x
mvn clean install -Dmaven.test.skip=true

git clone https://github.com/confluentinc/kafka-rest.git
git checkout origin/4.1.x
mvn clean install -Dmaven.test.skip=true

按照上述顺序，终于愉快的build了。。。

当然，如果没打算基于源码最改动，可以按照该项目Readme建议的，直接使用prebuilt版本
