[flink]#10_应用开发项目搭建

Java

Maven构建

$ mvn archetype:generate                               \
      -DarchetypeGroupId=org.apache.flink              \
      -DarchetypeArtifactId=flink-quickstart-java      \
      -DarchetypeVersion=1.9.0						\
      -DarchetypeCatalog=local

IDEA 导入后进行开发

或直接在pom.xml:

<dependency>  
  <groupId>org.apache.flink</groupId>  
  <artifactId>flink-java</artifactId>  
  <version>1.6.1</version> 
<scope>provided</scope>  
</dependency>  
<dependency> 
  <groupId>org.apache.flink</groupId>  
  <artifactId>flink-streaming-java_2.11</artifactId>  
  <version>1.6.1</version>  
  <scope>provided</scope>  
</dependency>

开发时注释scope，编译打包再开启

      -DarchetypeGroupId=org.apache.flink              \
      -DarchetypeArtifactId=flink-quickstart-scala      \

PS

一般的flink-java中的pom：

<dependencies> 
<!-- Apache Flink dependencies --> <!-- These dependencies are provided, because they should not be packaged into the JAR file. --> 
<dependency> 
<groupId>org.apache.flink</groupId> 
<artifactId>flink-java</artifactId> 
<version>${flink.version}</version>
 <scope>provided</scope> 
 </dependency> 
 <dependency> 
 <groupId>org.apache.flink</groupId>
  <artifactId>flink-streaming-java_${scala.binary.version</artifactId> 
<version>${flink.version}</version>
<scope>provided</scope> 
</dependency>

<!-- Add logging framework, to produce console output when running in the IDE. --> <!-- These dependencies are excluded from the application JAR by default. -> 
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.7</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
<scope>runtime</scope>
</dependency>
</dependencies>

为了使打出来的 Jar 包要小，又能够在本地 IDEA 中进行运行和调试 Job
