关于maven plugin executions 5C

请问各位大神,pom 中 build -> plugins -> plugin -> executions 下面的execution绑定的phase和goals是表示下面的哪一种:
1. 执行executions下面申明的其中一个phase的时候在goal阶段执行这个插件。
2. 执行这个插件的时候执行申明的所有phase。
3. 这个phase就是代表这个插件

1个回答

phase元素代表的是绑定的生命周期的阶段
goals元素代表插件的目标 插件是你前面artifactId中定义好的 goals相当于该插件中的一个功能 该功能将在phase绑定的生命周期阶段执行
这种方式属于自定义绑定 即在某个特定的生命周期阶段执行某个插件的功能 大多数时候是内置绑定的

所以1是有问题的 goal是一个插件的具体功能 而不是一个阶段 phase才是
2勉强是对的 一个插件可以对应多个生命周期阶段
3是错的 phase代表生命周期阶段

关于maven集成tomcat和jacoco进行手工测试覆盖率,但是没有成功

我现在想用tomcat7-maven-plugin和jacoco-maven-plugin集成,进行手工测试的覆盖率监控。 但是现在发现使用mvn tomcat7:shutdown不能关闭tomcat服务,即不能触发post-integration-test。 所以jacoco.exec就没有更新。所以想看看各位谁知道问题出在哪里?

Java校招入职华为,半年后我跑路了

何来 我,一个双非本科弟弟,有幸在 19 届的秋招中得到前东家华为(以下简称 hw)的赏识,当时秋招签订就业协议,说是入了某 java bg,之后一系列组织架构调整原因等等让人无法理解的神操作,最终毕业前夕,被通知调往其他 bg 做嵌入式开发(纯 C 语言)。 由于已至于校招末尾,之前拿到的其他 offer 又无法再收回,一时感到无力回天,只得默默接受。 毕业后,直接入职开始了嵌入式苦旅,由于从未...

C++(继承):19---虚基类与虚继承(virtual)

一、菱形继承 在介绍虚继承之前介绍一下菱形继承 概念:A作为基类,B和C都继承与A。最后一个类D又继承于B和C,这样形式的继承称为菱形继承 菱形继承的缺点: 数据冗余:在D中会保存两份A的内容 访问不明确(二义性):因为D不知道是以B为中介去访问A还是以C为中介去访问A,因此在访问某些成员的时候会发生二义性 缺点的解决: 数据冗余:通过下面“虚继承”技术来解决(见下) 访问...

计算机网络——浅析网络层

华为初面+综合面试(Java技术面)附上面试题

华为面试整体流程大致分为笔试,性格测试,面试,综合面试,回学校等结果。笔试来说,华为的难度较中等,选择题难度和网易腾讯差不多。最后的代码题,相比下来就简单很多,一共3道题目,前2题很容易就AC,题目已经记不太清楚,不过难度确实不大。最后一题最后提交的代码过了75%的样例,一直没有发现剩下的25%可能存在什么坑。 笔试部分太久远,我就不怎么回忆了。直接将面试。 面试 如果说腾讯的面试是挥金如土...

副业收入是我做程序媛的3倍,工作外的B面人生是怎样的?

提到“程序员”,多数人脑海里首先想到的大约是:为人木讷、薪水超高、工作枯燥…… 然而,当离开工作岗位,撕去层层标签,脱下“程序员”这身外套,有的人生动又有趣,马上展现出了完全不同的A/B面人生! 不论是简单的爱好,还是正经的副业,他们都干得同样出色。偶尔,还能和程序员的特质结合,产生奇妙的“化学反应”。 @Charlotte:平日素颜示人,周末美妆博主 大家都以为程序媛也个个不修边幅,但我们也许...

女朋友过生日,我花了20分钟给她写了一个代理服务器

女朋友说:“看你最近挺辛苦的,我送你一个礼物吧。你看看想要什么,我来准备。” 我想了半天,从书到鞋子到电子产品最后到生活用品,感觉自己什么都不缺,然后和她说:“你省省钱吧,我什么都不需要。” 她坚持要送:“不行,你一定要说一个礼物,我想送你东西了。” 于是,我认真了起来,拿起手机,上淘宝逛了几分钟,但还是没能想出来缺点什么,最后实在没办法了:“这样吧,如果你实在想送东西,那你就写一个代理服务器吧”...

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...
