【中文标题】grails 5`build/libs/`中的`-plain.war`是啥？【英文标题】：What is `-plain.war` in grails 5 `build/libs/`?grails 5`build/libs/`中的`-plain.war`是什么？ 【发布时间】：2022-01-09 18:02:56 【问题描述】：我使用grails 5官方start创建项目：
curl -O https://start.grails.org/restPproject.zip -d profile=rest-api
unzip restPproject.zip
cd restPproject
chmod +x gradlew grailsw
sed -i 's/org.grails.plugins:views-gradle:2.1.0/org.grails.plugins:views-gradle:2.1.1/' build.gradle
./grailsw war
而且我发现当我使用./grails war 时会在build/libs/ 中生成2 个war 文件：
$ ls build/libs/
restPproject-0.1-plain.war restPproject-0.1.war
-plain.war 是什么？我如何构建一个独立的可运行的战争，并且可以一次构建部署到像 Jetty 这样的 servlet 容器？
我发现-plain.war 和.war 都不能在 Jetty 10 下运行：
$ cp build/libs/restPproject-0.1-plain.war webapps/ROOT.war
$ docker run --rm -p 8080:8080 -v `pwd`/webapps:/var/lib/jetty/webapps/ jetty:10-jre11-slim

【问题讨论】：
“我怎样才能构建一个独立的可运行战争，并且可以一次构建部署到像 Jetty 这样的 servlet 容器？” - 你希望战争既可以独立运行，也可以部署到 Jetty？ @JeffScottBrown 最好能实现。否则一次构建2个war文件，一个可以独立运行，另一个可以部署到Jetty。谢谢。 "如果能实现就最好了。" -./gradlew assemble 给你你想要的吗？
@JeffScottBrown 不。这与./grails war 的结果相同，正如我的帖子所描述的那样。 -plain.war 和 .war 都不能在 Jetty 中运行。
我认为您看到的要么是配置错误的项目，要么是框架中的错误。目前尚不清楚应用程序为何尝试创建 tomcatServletWebServerFactory bean，但它可能在框架中出现问题。如果是这样，请在github.com/grails/grails-core/issues 提出问题。感谢您的反馈！
【参考方案1】：
在 Grails 5 中，有 3 种方式来打包您的应用程序：(1) grails package、(2) ./gradlew assemble 和 (3) grails war。他们都可以制作2个文件：myapp-0.1.war和myapp-0.1-plain.war。 (Grails Docs - 21 Deployment)
.war 文件在 3 种方式上是完全一致的，它是一个 Runnable WAR，所以你可以像这样运行它：java -jar build/libs/myapp-0.1.war。
-plain.war有点不同，在（1）和（3）的方式上是一致的，但是在（2）的方式中，WEB-INF/lib中增加了一个micronaut-inject-groovy-*.jar，它是NOT一个Runable WAR，用于Servlet容器部署，如Tomcat。
.war 和-plain.war 的区别在于用途不同。在.war 中有一个带有配置文件layers.idx 的spring-boot-jarmode-layertools-*.jar 比以前更容易Docker Deployment（不再需要手动解包），有关更多详细信息，请参阅 spring-boot 文档。(1.2. Layering Docker Images)

非常感谢。但是-plain.war 不能在 Jetty 下运行。怎么了？如何构建可以在 Jetty 下运行的-plain.war？谢谢。
".war 文件在 3 种方式上完全一致" - 3 种方式是什么？
@FengYu grails 文档说“2.11 支持的 Java EE 容器 - Jetty 8 或更高版本”，我看到您正在使用 docker 运行 Grails 项目。可以先尝试在jetty环境中直接运行-plain.war。
@JeffScottBrown 在 Grails 5 中，有 3 ways 来打包您的应用程序：(1) grails package, (2) ./gradlew assemble and (3) grails war
我熟悉如何构建 Grails 应用程序。是不是您所说的是您描述的所有 3 种技术都创建了具有相同内容的 .war 文件？以上是关于grails 5`build/libs/`中的`-plain.war`是啥？的主要内容，如果未能解决你的问题，请参考以下文章
