关于使用maven打包如何聚合资源文件

多数情况下,我们使用maven管理多个子工程,在最后maven打包阶段将多个子工程聚合到一个jar或war包。单个子工程会有自己独立的资源配置文件,在打包的时候我们需要将其聚合在一起(各子工程中的配置文件名称不能重复)。下面提供两种方法:

1.使用maven-resources-plugin插件,下面提供代码示例:

<build>
<finalName>${projectName}</finalName>
<plugins>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.5</version>
<executions>
<execution>
<id>copy-resources</id>
<phase>process-sources</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/target/classes/</outputDirectory>
<resources>
<!-- 将app.framecore中的配置文件复制到该宿主工程中 -->
<resource>
<directory>${basedir}/../../app.framecore/src/main/resources</directory>
<includes>
<include>**/*.sql</include>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
<!-- 将app.pms.cust.api中的配置文件复制到该宿主工程中 -->
<resource>
<directory>${basedir}/../app.pms.cust.api/src/main/resources</directory>
<includes>
<include>**/*.sql</include>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<compilerArgument>-parameters</compilerArgument>
<source>1.8</source>
<target>1.8</target>
<!-- true:跳过测试 -->
<skip>true</skip>
<encoding>${maven.compiler.encoding}</encoding>
</configuration>
</plugin>
</plugins>
</build>

2.直接在build节点中配置resources节点。如下代码所示:

<build>
<resources>
<resource>
<targetPath>${basedir}/target/classes/</targetPath>
<directory>${basedir}/../../app.framecore/src/main/resources</directory>
<includes>
<include>**/*.sql</include>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
<resource>
<targetPath>${basedir}/target/classes/</targetPath>
<directory>${basedir}/../app.pms.cust.api/src/main/resources</directory>
<includes>
<include>**/*.sql</include>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
</resources>
...
</build>

不过这里需要注意的是,一旦在build中指定了resources节点,必须自己手动添加所有待整合的资源文件。因为指定了resources,maven在打包时将严格按照用户指定的resources处理资源文件。所以这里推荐方法1.
