[常用maven配置]scala配置以及打包可运行JAR

说明

默认使用的IDE是IntelliJ IDEA。

scala配置

很多时候我们希望可以使用java+scala混合开发模式，此时只需要在maven进行如下配置即可：

<dependencies>
    <dependency>
      <groupId>org.scala-lang</groupId>
      <artifactId>scala-library</artifactId>
      <version>${scala.version}</version>
      <scope>compile</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
      <plugin>
        <groupId>org.scala-tools</groupId>
        <artifactId>maven-scala-plugin</artifactId>
        <version>2.15.2</version>
        <executions>
          <execution>
            <id>scala-compile-first</id>
            <goals>
              <goal>compile</goal>
            </goals>
            <configuration>
              <includes>
                <include>**/*.scala</include>
 </includes>
 </configuration>
 </execution>
 <execution>
 <id>scala-test-compile</id>
 <goals>
 <goal>testCompile</goal>
 </goals>
 </execution>
 </executions>
 </plugin>
 </plugins> 
</build> 

可运行jar打包

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>{此处填写main主类}</mainClass>
</transformer>
</transformers>
<filters> 
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
</execution>
</executions>
</plugin>
