Maven - 使用自定义的Class-Path构建manifest.mf

时间：2015-02-17 18:12:15

标签： maven classpath manifest.mf

我正在使用Maven构建一个包含20多个工件和~30个第三方工件的EAR项目。 EAR结构看起来像这样

EAR
+-project-artifact-1
+-project-artifact-2
...
+-project-artifact-n
+-lib/
| +-3rd-party-lib-1
| +-3rd-party-lib-2
| ...
| \-3rd-party-lib-n
\-META-INF/
包装工作正常。 我的问题是为MANIFEST.MF定制了Class-Path 我想使用Mavens功能使用

为我创建MANIFEST.MF 
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                        </manifest>
                    </archive>
                </configuration>
            </plugin>

我知道我可以使用classpathPrefix来设置前缀，但是这个前缀将被添加到所有依赖项中，无论它们的位置如何。 由于技术原因，我无法将所有JAR类型的工件放在lib文件夹中。 唯一的解决方法是将项目工件依赖项设置为scope provided，并使用manifestEntries手动将它们添加到类路径中。

我不喜欢这种解决方法，因为很难维护并有效地杀死我的依赖关系的传递性（我想保留它）。

我发现了这个example for a custom class-path，但我不知道如何将它用于我的目的。我的想法是使用属性来操作类路径，但似乎你只能使用工件的某些属性作为变量。

是否有其他方法来构建CP（除了使用手动维护的MF或手动维护poms中的CP条目）？

这是我的父pom看起来像（缩短）：
