Drools kie-ci 示例在 ubber jar 中失败，但在 eclipse IDE 中失败

Question

我已经尝试 drools 一个星期了，我正在尝试构建一个从本地 maven 存储库获取 kjar 的小型应用程序。如果我在 Eclipse 中运行我的应用程序，一切正常。如果使用 maven-shade-plugin 构建一个 ubber jar 并运行 java -jar myapp.jar 应用程序将失败，附件中提供了异常，尽管从本地 maven 存储库中充分读取了 kjar 工件（我通过提供非现有的工件，它给出了一个正确的错误）。

我现在搜索了将近一天，但无法在 drools 文档、github 上提供的示例或 Google 索引的任何其他页面中找到解释：-/ 我不知道它是否相关到 ubber jar，因为所有示例都没有提到它们如何部署应用程序。请帮帮我！

我正在附加堆栈跟踪的一部分以及异常和我的 pom.xml。我没有更改任何与 Maven 相关的 settings.xml，因为该应用似乎可以正确地从本地存储库中检索信息。

堆栈跟踪

将此配置添加到 maven-shade-plugin 后。所以我怀疑这确实是一个与 maven-shade-plugin 相关的问题，但我不知道另一种构建 ubber jar 以在应用程序中使用 Drools 的方法。

<transformer
                    implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">                                  
                                        <resource>META-INF/sisu/javax.inject.Named</resource>                                   
                                </transformer>

我们让 Drools 从 uber-JAR 运行，并为 maven-shade-plugin 配置以下配置。

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <configuration>
      <createDependencyReducedPom>true</createDependencyReducedPom>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <transformers>
            <!-- some transformers omitted -->
            <transformer
              implementation="org.apache.maven.plugins.shade.resource.ComponentsXmlResourceTransformer" />
            <transformer
              implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/kie.conf</resource>
            </transformer>
            <transformer
              implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/sisu/javax.inject.Named</resource>
            </transformer>
          </transformers>
        </configuration>
      </execution>
    </executions>
  </plugin>

它与您的解决方案的不同之处在于添加了“org.apache.maven.plugins.shade.resource.ComponentsXmlResourceTransformer”转换器。希望能帮助到你。

最好的问候！

这实际上只是我的 2 美分，因为此刻你想要做的事情超出了我的想象。

但我确实在您的堆栈跟踪中看到了 '1057 [main] WARN org.appformer.maven.integration.embedder.MavenSettings - 未设置环境变量 M2_HOME'

1. (Win7) 控制面板/系统/高级系统设置 -> 系统属性弹出/选项卡高级/按钮“环境变量” -> 环境变量弹出，底部窗口“系统变量”。
2. 确保你有一个 M2_HOME 和 MAVEN_HOME 条目指向你的 maven 安装；必要时编辑或添加。

这可能是您的 MavenEmbedder 无法构建的原因。
