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

Question

我尝试使用：

• Java11
• RestEasy 4.1.0最终版
• 码头9.4.19. v20190610
• gretty-gradle-plugin来自https://raw.github.com/gretty-gradle-plugin/gretty/master/pluginScripts/gretty.plugin

使用下面的子项目构建。格雷德尔：

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，当我试图运行我的服务器使用：gradlew清洁构建runApp我得到以下异常：

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了解决方案吗？

Answer 1

我在主build.gradle的构建脚本方法中使用Getty libs依赖：

buildscript {
  repositories {
        maven {
            url mirrorRepoUrl
        }
   }

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

这应该只为Gradle CL添加Gretty libs，如果您使用的是grettyRunnerJetty94，该lib在服务器运行时可用，但它不包括在build for WAR中（这正是我想要的，所以我要感谢您）。
