gradle - 如何用gradle构建WAR文件？

Question

我想构建一个WAR文件(然后将其部署到Tomcat)。因此，作为练习，我在IDEA IntelliJ中使用Gradle启动了一个新的Spring Boot项目。之后，我将插件应用在build.gradle文件中，例如apply plugin: 'war'。

问题是，当我尝试在终端中运行gradle war时，没有收到war文件!唯一发生的是它将生成一个带有3个子焊料\build，classes和resources的tmp，但是其中没有WAR。

我应该怎么做才能获得WAR文件？我看过this视频，但是这个人使用Maven，并且不做任何高级工作而是打仗。我认为必须有一种使其保持简单的方法。

当我运行gradle war --info

Initialized native services in: C:\Users\...\.gradle\native The client 

...

我猜您除了war插件之外，还已经将spring boot gradle插件应用到了您的项目中？那么这种行为是正常的，因为Spring Boot插件将禁用jar和war任务，并将其替换为bootWar和bootJar任务。

在同时使用spring boot和war插件的情况下:

./gradlew war
15:35:09: Executing task 'war'...

> Task :compileJava UP-TO-DATE
> Task :processResources UP-TO-DATE
> Task :classes UP-TO-DATE
> Task :war SKIPPED

BUILD SUCCESSFUL in 0s
2 actionable tasks: 2 up-to-date
15:35:10: Task execution finished 'war'.

注意“跳过”消息

$ ./gradlew bootWar
15:36:35: Executing task 'bootWar'...

> Task :compileJava UP-TO-DATE
> Task :processResources UP-TO-DATE
> Task :classes UP-TO-DATE
> Task :bootWar

BUILD SUCCESSFUL in 1s
3 actionable tasks: 1 executed, 2 up-to-date
15:36:37: Task execution finished 'bootWar'.

然后，您将在build/libs下获得预期的war文件。

您仍然可以按照以下说明重新启用标准的jar/war任务: https://docs.spring.io/spring-boot/docs/current/gradle-plugin/reference/html/#packaging-executable-wars-deployable(如果您需要生成普通存档而不是可执行存档)
