73.5. 使用排除创建不可执行的JAR

如果你构建的产物既有可执行的jar和非可执行的jar，那你常常需要为可执行的版本添加额外的配置文件，而这些文件在一个library jar中是不需要的。比如，application.yml配置文件可能需要从非可执行的JAR中排除。

下面是如何在Maven中实现：

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <classifier>exec</classifier>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-jar-plugin</artifactId>
            <executions>
                <execution>
                    <id>exec</id>
                    <phase>package</phase>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                    <configuration>
                        <!-- Need this to ensure application.yml is excluded -->
                        <forceCreation>true</forceCreation>
                        <excludes>
                            <exclude>application.yml</exclude>
                        </excludes>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

在Gradle中，你可以使用标准任务的DSL（领域特定语言）特性创建一个新的JAR存档，然后在bootRepackage任务中使用withJarTask属性添加对它的依赖：

jar {
    baseName = 'spring-boot-sample-profile'
    version =  '0.0.0'
    excludes = ['**/application.yml']
}

task('execJar', type:Jar, dependsOn: 'jar') {
    baseName = 'spring-boot-sample-profile'
    version =  '0.0.0'
    classifier = 'exec'
    from sourceSets.main.output
}

bootRepackage  {
    withJarTask = tasks['execJar']
}
