这里有各种非常常用的构建插件

打包插件

如果需要指定主类，可以使用maven-jar-plugin插件打包

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>3.2.2</version>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <mainClass>${main.class}</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>

依赖插件

如果需要将其他依赖打包进这个jar包中，可以使用maven-assembly-plugin插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.3.0</version>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals> <goal>single</goal> </goals>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>${main.class}</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </execution>
    </executions>
</plugin>

Kotlin

如果想要在Maven中使用Kotlin，需要kotlin-maven-plugin插件

https://kotlinlang.org/docs/maven.html

基本设置

将下面的内容写在properties中

<kotlin.version>1.7.0</kotlin.version>

打包只有Kotlin的文件

<plugin>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-maven-plugin</artifactId>
    <version>${kotlin.version}</version>
    <executions>
        <execution>
            <id>compile</id>
            <goals>
                <goal>compile</goal>
            </goals>
        </execution>
        <execution>
            <id>test-compile</id>
            <goals>
                <goal>test-compile</goal>
            </goals>
        </execution>
    </executions>
</plugin>

将下面的内容写在build中

<sourceDirectory>${project.basedir}/src/main/kotlin</sourceDirectory>
<testSourceDirectory>${project.basedir}/src/test/kotlin</testSourceDirectory>

打包同时包含Java和Kotlin的文件

<plugin>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-maven-plugin</artifactId>
    <version>${kotlin.version}</version>
    <executions>
        <execution>
            <id>compile</id>
            <goals>
                <goal>compile</goal>
            </goals>
            <configuration>
                <sourceDirs>
                    <sourceDir>${project.basedir}/src/main/kotlin</sourceDir>
                    <sourceDir>${project.basedir}/src/main/java</sourceDir>
                </sourceDirs>
            </configuration>
        </execution>
        <execution>
            <id>test-compile</id>
            <goals> <goal>test-compile</goal> </goals>
            <configuration>
                <sourceDirs>
                    <sourceDir>${project.basedir}/src/test/kotlin</sourceDir>
                    <sourceDir>${project.basedir}/src/test/java</sourceDir>
                </sourceDirs>
            </configuration>
        </execution>
    </executions>
</plugin>

同时，你还需要Java编译插件maven-compiler-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.10.1</version>
    <executions>
        <!-- Replacing default-compile as it is treated specially by maven -->
        <execution>
            <id>default-compile</id>
            <phase>none</phase>
        </execution>
        <!-- Replacing default-testCompile as it is treated specially by maven -->
        <execution>
            <id>default-testCompile</id>
            <phase>none</phase>
        </execution>
        <execution>
            <id>java-compile</id>
            <phase>compile</phase>
            <goals>
                <goal>compile</goal>
            </goals>
        </execution>
        <execution>
            <id>java-test-compile</id>
            <phase>test-compile</phase>
            <goals>
                <goal>testCompile</goal>
            </goals>
        </execution>
    </executions>
</plugin>

添加依赖

<dependency>
    <groupId>org.jetbrains.kotlin</groupId>
    <artifactId>kotlin-stdlib</artifactId>
    <version>${kotlin.version}</version>
</dependency>
