java - Gretty/Jetty 无法使用 java 11、Jetty 9.4.14、gretty 加载 WebAppContext

Question

我尝试使用:

• Java 11
• RestEasy 4.1.0.Final
• Jetty 9.4.19.v20190610
• 来自 https://raw.github.com/gretty-gradle-plugin/gretty/master/pluginScripts/gretty.plugin 的 gretty-gradle-plugin

使用以下子项目 build.gradle :

apply plugin: 'war'
apply from: 'https://raw.github.com/gretty-gradle-plugin/gretty/master/pluginScripts/gretty.plugin'

gretty {
    jacocoEnabled false
}

war{
    archiveName project.name+".war"
}

gretty {
  servletContainer = 'jetty9.4'
  httpPort = 8081
}

dependencies {
    [...]
    grettyRunnerJetty94 group: 'org.eclipse.jetty', name: 'jetty-runner', version: '9.4.19.v20190610'
}

但是当我尝试使用: gradlew clean build runApp 运行我的服务器时，出现以下异常:

14:53:16 WARN  org.jboss.resteasy.plugins.server.servlet.HttpServlet30Dispatcher defines neither @WebServlet.value nor @WebServlet.urlPatterns

服务器没有加载我的 Servlet...

有人遇到过这个问题并找到解决方案吗？

Answer 1

我在 master build.gradle 的 buildscript 方法中使用 Getty libs 依赖项:

buildscript {
  repositories {
        maven {
            url mirrorRepoUrl
        }
   }

  dependencies {
    classpath 'org.gretty:gretty:+'
  }
}

这应该仅为 Gradle CL 添加 Gretty 库，如果您使用的是 grettyRunnerJetty94，则该库在服务器运行时中可用，但它不包含在 WAR 的构建中(这正是我所寻找的，所以我想感谢您)。
