this blogpost 这演示了在ratpack中阻塞处理程序,但我无法使其工作。我正在获取背景的缺失方法异常。

我的身材。gradle文件如下 this GitHub directory

buildscript {
    repositories {
    maven { url "http://oss.jfrog.org/artifactory/repo" }
    jcenter()
  }
  dependencies {
    classpath 'io.ratpack:ratpack-gradle:0.9.4'
  }
}

apply plugin: "ratpack-groovy"
apply plugin: "idea"
apply plugin: "eclipse"

repositories {
  maven { url "http://oss.jfrog.org/artifactory/repo" }
  jcenter()
  maven { url "http://repo.springsource.org/repo" }
  maven { url "https://nexus.codehaus.org/content/repositories/snapshots/" }
}

dependencies {
  springloaded "org.springsource.loaded:springloaded:1.1.5.RELEASE"

  testCompile "org.spockframework:spock-core:0.7-groovy-2.0", {
      exclude module: "groovy-all"
  }
}

// The Groovy that rest-assured drags in via ratpack-groovy-test is toxic, prevent it from coming in
// This should be fixed upstream in Ratpack
configurations.testCompile.dependencies.find { it.name == "ratpack-groovy-test" }.exclude(group: "org.codehaus.groovy")

import static ratpack.groovy.Groovy.ratpack

    ratpack {
        handlers {
            get("non-blocking") {
                background {
                    Thread.sleep(10000)
                }.then{
                    response.send()
                }
            }
        }
    }

我正在获取背景的缺失方法异常。

groovy.lang.MissingMethodException: No signature of method: nonBlocking.background() is applicable for argument types: (nonBlocking$_run_closure1$_closure2$_closure3$_closure4) values: [nonBlocking$_run_closure1$_closure2$_closure3$_closure4@497352d0]

background 已被替换为 Blocking.get

3.5-rc-2 版本和do

./gradlew test

它将失败,并出现以下错误:

FAILURE: Build failed with an exception.

* Where:
Build file '/home/wololock/workspace/idea/stackoverflow-answers/46009278/build.gradle' line: 11

* What went wrong:
A problem occurred evaluating root project '46009278'.
> Failed to apply plugin [id 'ratpack-groovy']
   > Could not find method groovy() for arguments [DefaultExternalModuleDependency{group='io.ratpack', name='ratpack-groovy', version='0.9.4', configuration='default'}] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

现在,如果我们看看这个例子开发时使用了什么Gradle版本,我们会发现它使用了Gradle 1.10 gradle-wrapper.properties 文件:

#Sun Jul 21 19:00:37 CDT 2013
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-bin.zip

如果定义相同的Gradle包装器版本并执行以下操作:

./gradlew试验

或

./gradlew runFatJar

10:39:44: Executing external task 'runFatJar'...
The groovy configuration has been deprecated and is scheduled to be removed in Gradle 2.0. Typically, usages of 'groovy' can simply be replaced with 'compile'. In some cases, it may be necessary to additionally configure the 'groovyClasspath' property of GroovyCompile and Groovydoc tasks.
