如何使用 cargo-maven2-plugin 为嵌入式 Jetty 指定 Java 系统属性

Question

我正在尝试使用 Maven Cargo 插件为我的项目的集成测试启动一个嵌入式 Jetty 容器。使用 Jetty 托管的 Web 应用程序需要传递一个指向其配置文件的 Java 系统属性。如何让它与 Cargo 一起使用？

我已经尝试了插件cargo.jvmargs 设置，但它似乎不起作用：

<plugin>
    <!-- Launch an embedded Jetty instance hosting this project's WAR (as 
        well as the rps-tourney-service-app WAR it depends on) prior to running this 
        project's integration tests, and stop it after the integration tests. Alternatively, 
        for manual testing, manually run 'mvn cargo:run' to start the Jetty server, 
        and have Cargo wait for a 'ctrl+c' command to stop it. -->

webapps 按预期启动，但随后由于未找到预期的配置属性而死。

想通了。我一直担心嵌入式 Jetty（或其他嵌入式容器）无法做到这一点，但事实是：我只是错误地传递了系统属性。

请改用<container><systemProperties><someProp>someVal</someProp></systemProperties></container> 选项。例如：

<plugin>
    <!-- Launch an embedded Jetty instance hosting this project's WAR (as 
        well as the rps-tourney-service-app WAR it depends on) prior to running this 
        project's integration tests, and stop it after the integration tests. Alternatively, 
        for manual testing, manually run 'mvn cargo:run' to start the Jetty server, 
        and have Cargo wait for a 'ctrl+c' command to stop it. -->

一切都按预期进行。耶！
