Question

使用Spring应用程序并使用Maven 3作为构建工具。我的应用程序在Windows计算机上的Eclipse Neon中运行正常。

现在我在Mac系统上使用Oxygen。我的应用需要特定的上下文根，即/app。

当我通过更改.settings/org.eclipse.wst.common.component文件或Web项目设置属性来设置上下文根后，对其进行更新（maven更新）时，它再次将上下文根恢复为app。

这是我的pom.xml

还有其他方法可以更改上下文根吗？是否知道为什么Maven更新了上下文根？

Answer 1

在使用Maven项目时，IDE通常会从POM文件中导入设置，因此应更改POM而不是更改IDE设置，并且在更新时会自动将其导入。 / p>

在您的情况下，请尝试在wtpContextName中更改finalName，POM并更新/重新导入。

Answer 2

请参见M2E-WTP FAQ。它说，指定

<properties>
   <m2eclipse.wtp.contextRoot>/app</m2eclipse.wtp.contextRoot>
   ...
 </properties>

可以解决问题。至少在Eclispe 2018-12（4.10.0）和M2E 1.10.0上对我有用

像this这样的较旧的解决方案似乎无效。
