+### 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：
+```xml
+<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：
+```gradle
+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']
+}
+```
