利用maven在一個項目中同時打war包和jar包

把項目的打包類型設置稱war

<packaging>war</packaging>

然後添加：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <executions>
        <execution>
            <id>make-a-jar</id>
            <phase>compile</phase>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        ...
    </configuration>
</plugin>

以及：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.3</version>
    <configuration>
        ...
    </configuration>
</plugin>
