从 Tomcat 8 开始，Cargo 在后台

Question

我正在尝试运行使用 Cargo 和 Tomcat 8（安装模式）的 Web 应用程序。我将 Tomcat 作为 maven 的后台进程启动（默认情况下，cargo:run 阻止控制台，等待 Ctrl+C），所以我将 cargo.process.spawn 属性设置为 true，但我得到以下输出：

[INFO] Scanning for projects...

我尝试将 timeout 设置为 0，但没有任何改变。

这是我用来部署网络应用程序的pom.xml：

编辑：

我认为这是一个错误，因为 org.codehaus.cargo.container.spi.jvm.DefaultJvmLauncherFactory class 设置了很多与生成模式不兼容的硬编码参数（参见 this 行）。

Answer 1

它应该在 Cargo 版本 1.6.3 中修复。

从 Tomcat 8 开始，Cargo 在后台

Starting Tomcat 8 with Cargo in background

background-process

spawn

maven

tomcat8
