maven - 阻止插件执行生命周期阶段

Question

我使用以下命令序列调用 maven

C:>\mvn install tomcat7:redeploy

这会产生以下(大量)编辑的输出

[INFO] --- maven-resources-plugin:2.6:resources (default-resources) @ geomaster ---
[INFO] Copying 0 resource
[INFO] --- maven-compiler-plugin:2.5.1:compile (default-compile) @ geomaster ---

请忽略我的项目中没有资源或源代码的事实。这不是问题的关键。

install目标用于将生成的war放入maven存储库中。 tomcat7:redeploy 目标用于将生成的 war 放入 tomcat 服务器中。

我尝试了各种调用和不同的配置，但我无法阻止 tomcat 插件执行它自己的构建，尽管 install 目标刚刚完成了它。

surefire 插件似乎有一些“智能”，因为它检测到它之前已经运行过。为什么 Maven 不能也有这种“智能”？

有关 tomcat 插件的其他信息可以在这里找到:tomcat7-maven-plugin

虽然由 tomcat 插件执行的第二个构建不会做任何实质性的事情，即使在一个更实质性的项目中，我怎样才能阻止它被执行，因为它完全是多余的？

这是 Maven 或 tomcat 插件中的错误吗？这可以作为请求增强的基础吗？或者这种预期的行为必须忍受？

从您链接到的 Tomcat 页面了解 deploy goal ，它指出:

Invokes the execution of the lifecycle phase package prior to executing itself.

这就是它自己构建的原因。这是一个有意为之的功能，据我所知无法关闭。

但是deploy-only目标存在:

Deploy a WAR to Tomcat without forking the package lifecycle

因此，如果您将命令更改为:

mvn install tomcat7:deploy-only

那么它应该做你想做的事。
