【flink-开发】IntelliJ IDEA开发

准备

Maven 3.0.4 （或更高版本）和 安装 Java 8.x
cmd

mvn archetype:generate -DarchetypeGroupId=org.apache.flink -DarchetypeArtifactId=flink-quickstart-scala -DarchetypeVersion=1.6.2
#若只使用Java
#mvn archetype:generate -DarchetypeGroupId=org.apache.flink -DarchetypeArtifactId=flink-quickstart-java -DarchetypeVersion=1.6.2

或者 git clone https://github.com/liangriyu/flink-quickstart.git

一、IntelliJ IDEA配置

1、安装Scala插件

1、Go to IntelliJ plugins settings (IntelliJ IDEA -> Preferences -> Plugins) and click on “Install Jetbrains plugin…”.
2、Select and install the “Scala” plugin.
3、Restart IntelliJ

2、导入flink项目

启动idea或者全部关闭当前打开项目（file->Close Project）,选择“Import Project”->maven

二、测试运行及打包

1. 通常情况下，在IDEA中编写完代码直接运行main方法测试程序即可。
2. 打jar包部署到flink集群：
   方式1：直接使用maven插件管理（推荐）

<plugins>

            <!-- Java Compiler -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>${maven.compiler.source}</source>

                </configuration>
            </plugin>

            <!-- We use the maven-shade plugin to create a fat jar that contains all necessary dependencies. -->
            <!-- Change the value of <mainClass>...</mainClass> if your program entry point changes. -->

                                    <!-- Do not copy the signatures in the META-INF folder.
                                    Otherwise, this might cause SecurityExceptions when using the JAR. -->

                                    <excludes>
                                        <exclude>META-INF/*.SF</exclude>
                                        <exclude>META-INF/*.DSA</exclude>

                            <transformers>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <mainClass>org.apache.flink.StreamingJob</mainClass>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>

方式2：手动加入依赖（如下）
file ->ProjectStructrue ->Artifacts
