+### 73.4. 在可执行jar运行时提取特定的版本
+
+在一个可执行jar中，为了运行，多数内嵌的库不需要拆包（unpacked），然而有一些库可能会遇到问题。例如，JRuby包含它自己的内嵌jar，它假定`jruby-complete.jar`本身总是能够直接作为文件访问的。
+
+为了处理任何有问题的库，你可以标记那些特定的内嵌jars，让它们在可执行jar第一次运行时自动解压到一个临时文件夹中。例如，为了将JRuby标记为使用Maven插件拆包，你需要添加如下的配置：
+```xml
+<build>
+    <plugins>
+        <plugin>
+            <groupId>org.springframework.boot</groupId>
+            <artifactId>spring-boot-maven-plugin</artifactId>
+            <configuration>
+                <requiresUnpack>
+                    <dependency>
+                        <groupId>org.jruby</groupId>
+                        <artifactId>jruby-complete</artifactId>
+                    </dependency>
+                </requiresUnpack>
+            </configuration>
+        </plugin>
+    </plugins>
+</build>
+```
+使用Gradle完全上述操作：
+```gradle
+springBoot  {
+    requiresUnpack = ['org.jruby:jruby-complete']
+}
+```
