在 Maven 中运行 org.mule.MuleServer 导致 SecurityException

Question

我有以下 Maven 构建配置文件：

    <profile>
        <id>runMule</id>
        <activation>
            <property>
                <name>runMule</name>
            </property>
        </activation>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>exec-maven-plugin</artifactId>
                    <configuration>
                        <executable>java</executable>
                        <arguments>
                            <argument>-classpath</argument>
                            <classpath/>
                            <argument>org.mule.MuleServer</argument>
                            <argument>-config</argument>
                            <argument>mule-config.xml</argument>
                        </arguments>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>

如果我执行：

mvn exec:exec -DrunMule

我以以下错误结束：

[INFO] --- exec-maven-plugin:1.2.1:exec (default-cli) @ acceptance-tests ---

我认为这是 Maven 依赖项冲突，但我不确定。

知道是什么导致了错误吗？

Answer 1

我同意，这看起来像是依赖冲突。你有日食吗？如果这样做，您可以在 pom.xml 的“依赖关系层次结构”选项卡中看到冲突。这是我的依赖层次结构的屏幕截图。

Answer 2

请留意其他人:)您已经在使用maven，运行“mvn dependency:tree”和“mvn dependency:list”来解决依赖问题，这样您也可以在此处发布结果。
