将.properties文件与Apache shades插件合并

Question

我正在尝试使用shades插件将出现在两个依赖项(openwebbeans-impl，openejb- openwebbeans.properties )中的核心文件合并到我的一个OSGi包中。我按照shades文档进行配置，如下所示https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#AppendingTransformer

   <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-shade-plugin</artifactId>
         <version>2.3</version>
         <executions>
               <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                   <resource>META-INF/openwebbeans/openwebbeans.properties</resource>
                             </transformer>
                        </transformers>
                    </configuration>
                </execution>
           </executions>
    </plugin>

但是当我尝试mvn全新安装时，它失败了，错误如下

[INFO] --- maven-shade-plugin:2.3:shade (default) @ tomee ---
[ERROR] The project main artifact does not exist. This could have the following
[ERROR] reasons:
[ERROR] - You have invoked the goal directly from the command line. This is not
[ERROR]   supported. Please add the goal to the default lifecycle via an
[ERROR]   <execution> element in your POM and use "mvn package" to have it run.
[ERROR] - You have bound the goal to a lifecycle phase before "package". Please
[ERROR]   remove this binding from your POM such that the goal will be run in
[ERROR]   the proper phase.
[ERROR] - You removed the configuration of the maven-jar-plugin that produces the main artifact.
[INFO] ------------------------------------------------------------------------

有人能告诉我我的配置中有什么错误吗？执行此操作的正确方法是什么？

根据struberg提供的答案，我的尝试似乎不适用于openwebebans上下文。但是我仍然想知道合并属性文件的正确方式是什么。或者如何解决这个问题。

Answer 1

棘手的部分是我们在每个文件中都有一个'configuration.ordinal‘属性。这定义了信息被“合并”的顺序。较高的序数值稍后将应用于较低的序数配置。因此，来自较高序号配置的配置设置将保持不变。
