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应用程序需要传入一个指向其配置文件的Java系统属性。我如何让它与货物一起工作？

我尝试过插件的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. -->

</plugin>

not应用程序按预期启动，但随后由于找不到预期的配置属性而终止。

我想通了。我一直担心这对于嵌入式Jetty (或其他嵌入式容器)来说是不可能的，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. -->

事情就像预期的那样工作。耶！
