我正在创建一个示例jenkins管道,这里是代码.

pipeline {
    agent any 

    stages {    
        stage('test') { 
            steps { 
                sh 'echo hello'
            }            
        }
        stage('test1') { 
            steps { 
                sh 'echo $TEST'
            }            
        }
        stage('test3') {
            if (env.BRANCH_NAME == 'master') {
                echo 'I only execute on the master branch'
            } else {
                echo 'I execute elsewhere'
            }                        
        }        
    }
}

此管道失败,并显示以下错误日志

Started by user admin
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 15: Not a valid stage section definition: "if (env.BRANCH_NAME == 'master') {

我是scala的新学习者,我正在尝试运行此示例代码

 def isLast(c: Int, r: Int):Int ={
   if(r == 1)
   {
   return 1;
   }

  else if (r == c){
   return 1
    }
   }

但它给了我编译时错误,说

Multiple markers at this line
- type mismatch;  found   : Unit  required: Int
- type mismatch;  found   : Unit  required: Int

请帮助我,并建议我学习scala的一些好网站.

我想在ubuntu 12.04上安装git.但是当输入命令时

sudo apt-get install git

我收到以下消息.我已经跑过sudo apt-get update了.

This may mean that the package is missing, has been obsoleted, or

我有一个指令,并在其链接功能,我想从服务访问方法.我的指令代码是

AppDirectives.directive('feed',['FeedService',function() {
return {
    restrict : 'AE',
    scope : {
        feedLike: '&',
        feedItem : '=',
        feedDislike :'&',
        feedsArray :'=',
    },
    templateUrl :'resources/views/templates/feedTemplate.html',

    link : function(scope,element,feedService){
        console.debug("linking now");
        scope.likeComment = function(commentUid){
            console.debug("comment liked :"+commentUid);
        };

        scope.addComment = function(referenceFeedUid){
            console.debug("commentText : "+scope.commentText);
            var comment = {
                    user : "guest",
                    feedText : scope.commentText
                };
            feedService.addComment(comment,referenceFeedUid).then(function(response){
                console.debug("response ; "+response);
            //  $scope.feeds.unshift(response);
            });
        };

    },
    replace : true,

};
}]);

我的服务代码是

.factory('FeedService',function($http){

return {
    postFeed : function (feed){
        /*$http.post('/feed/add',feed).success(function(response){
            console.debug("added "+response);
        }).error(function(){
            console.debug("error adding …

这是我正在尝试执行的Jenkins管道.我正在关注本教程:

pipeline {
    agent any
    stages {
        stage('one') {
            parallel "first" : {               
                    echo "hello"                
            },
            "second": {                
                    echo "world"            
            }
        }
        stage('two') {
            parallel "first" : {               
                    echo "hello"                
            },
            "second": {                
                    echo "world"            
            }
        }
    }
}

但是这项工作失败了以下信息.

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

当我写html时,我添加了所有类

<div class="col-lg-8 col-lg-offset-2 col-md-8 col-md-offset-2 col-sm-8 col-sm-offset-2 col-xs-8 col-xs-offset-2"></div>

我看过很多教程,但从未见过有人将所有类添加到每个div中.

包括所有课程是一种好习惯吗？

我只想知道JUnit测试中times(0)和never()之间的区别是什么.

例如,我有用于在mongoDB中保存数据的测试行代码:

verify(mockRepository,never()).save(any(User.class));

如果我把它写成:

verify(mockRepository,times(0)).save(any(User.class));

两个测试都显示save方法没有调用.(如果我错了,请纠正我)这两者有什么区别吗？

我在pom.xml中添加了依赖项

<dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.1</version>
        </dependency>

但是当我更新maven依赖项并导入EscapeStringUtils使用时

import org.apache.commons.lang3.StringEscapeUtils;

我得到红色下划线和错误,其中指出:

The import org.apache.commons.lang3.StringEscapeUtils cannot be resolved

Jar文件在那里(已下载)现在如何解决它,我不知道.请帮助我.

谢谢

我正在尝试创建一个按钮,上面有一些文字.但是文本没有包裹在按钮上.这就是我所做的.

<div class="form-group">
  <div class="col-md-6 col-sm-6 col-xs-6">
    <input type="radio" id="1" class="hidden">
    <label for="1" class="btn btn-info btn-preference  pull-right">Stability</label> 
  </div>
  <div class="col-md-6 col-sm-6 col-xs-6">
    <input type="radio" id="1" class="hidden">
    <label for="1" class="btn btn-primary btn-preference text-center">
      <span class="break-wo">Freedom and Risk</span>                                                        
    </label>

我试图通过ajax帖子将数据发布到spring控制器.我的ajax代码是

function postData(tag){
console.debug(tag);

var targetUrl = "/add/tag";
$.ajax({
    url : targetUrl,
    type : "POST",
    data : tag,
    dataType : "text",
    success : function(response){
        console.debug(response);
    },
    error : function(){
        console.debug("error : ".concat(response));
    }
});
}

我的控制器代码是

@RequestMapping(value = "/add/tag", method = POST, consumes = { "application/json" },headers = "content-type=application/x-www-form-urlencoded")
@ResponseBody
public Integer addTag(HttpServletRequest request,
    @PathVariable("uid") String gatheringUid, @RequestBody String tag) {
    System.out.print(tag);
    return gatheringService.updateGathering(gatheringUid, tags);
}

在服务器端,它打印附加"="符号的标签的值,而在firebug控制台上的值打印为我输入.

例如,当我发布数据"test"时,在firebug控制台上打印"test",在服务器端控制台上打印"test =".

任何人都可以告诉我这里有什么问题.

在此先感谢,问候.
