java工具:git得使用及maven私服搭建_git直接配置到私有化maven搭建

本文详细介绍git在项目开发过程中得使用,及maven github私服得搭建

Git:分布式版本控制系统(SVN集中式版本控制系统)
svn:只有一台中央服务器,一起下载代码,一起提交代码
git:每个人都有自己的本地版本库,将自己的代码推送给别人
下载地址:https://git-scm.com/download/win

安装完成:右键选择Git Bash Here 进入命令行
配置:$ git config --global user.name “Your Name”
$ git config --global user.email "email@example.com"
安装配置完毕====
基本命令:
1.创建本地版本库,进入文件夹右键选择Git Bash Here 执行git init
2.新建文件:(touch/vi a.txt)
3.git status(查看文件是否纳入版本库)
4.git add a.txt (纳入git暂存区)
5.git commit -m “提交注释”(纳入到版本库)
6.git log a.txt (查看操作日志/git log --pretty=oneline a.txt 一行显示日志)
7.git diff a.txt (查看工作空间和本地库的差异)
8.git reset --hard HEAD(回退到上一版本) 9.git reflog a.txt(查看所有的操作记录并带有版本号) 10.git reset --hard HEAD 9中的版本号(回到某个版本) 11.git reset --hard HEAD3(回到第3版本)
12.git checkout --a.txt回撤版本(回撤的是自己的本地空间)
三区：
工作区:自己的电脑
暂存区:工作去add到暂存区
版本区:暂存区commit到版本区
push到git服务器

创建分支:
1.git branch 查看分支
2.git branch name 分支创建(会把master主分支东西带过来)
3.git checkout dev 切换分支dev
4.git branch master/切换到主分支 git merge dev/将dev分支合并到master
5.解决合并冲突:
cat 冲突文件===>删除掉<<<<>>>>====符号
在进行提交
6.git branch -d dev 删除分支
7.git branch -b test新建切换到分支

github:托管git项目
一:本地上传远程库
1.在git上新建项目
2.在本地git命令行执行:git remote add origin https://github.com/SongFuShuang/ao-test.git连接到github服务器
3.git push -u origin master 将本地项目推送到github服务器
4.编辑本地文件–>add—>commit—>git push origin master 推送到远程库
5.远程库更改:git pull origin master—>下载到本地
二:从github服务器下载代码
1.git clone https://github.com/SongFuShuang/ao2.git

三:fork:使用fork相当于你在原项目的主分支上又建立了一个分支，你可以在该分支上任意修改。如果想将你的修改合并到原项目中时，可以pull requests
(接收到其他用户得fork后同意后合并)
四:图形化工具TortoiseGit:地址https://download.tortoisegit.org
1.创建仓库:新建文件—>先add("+")—>commit(“√”) 回退:reset master to this commit是重置master中选择Hard其余得都被干掉不会保留
回撤/还原:revert change by this commit 把提交得版本还原到上一个版本(双重revert能找回之前得还原)
2.创建分支:
先create branch 在switch/checkout切换分支 修改分支内容commit 在switch/checkout切换到主分支,在merge
冲突解决:edit conflicts冲突解决
3.远程库操作连接:push pull
4.Egit:eclipse得插件(有的eclipse整合好了有的没有)
配置:Git–>Configuration—>配置用户名密码(也可能会有的整合SSH私钥)
eclipse项目上传git时:
项目share后会出现?在各个文件上,之后在右键add index加入到本地库出现+号 commit后变为黄色药瓶
推送到远程:Remote–>push
更新代码:Pull
可能会报错:The current branch is not configured for pull
No value for key remote.origin.url found in configuration
解决:Git–>Configuration–>Repository Setting 如图1:

添加如下:
[branch “master”]
remote = origin
merge = refs/heads/master
[remote “origin”]
url = https://github.com/androidzhaoxiaogang/rocket.git（修改为自己的url）
fetch = +refs/heads/:refs/remotes/origin/
push = refs/heads/master:refs/heads/master
小操作:
当服务器比自己得代码新:可以使用synchronized Workspace同步代码 会切换到视图:共四个图标 分别代表:服务器最新 本地最新 服务器本地最新 冲突
eclipse解决冲突:先pull整理完在add index 在push

maven私服搭建:
maven私服好处:1.节约外网带宽2.加速maven的构建3.部署自己的基础类库

jdk1.8 maven Nexus-2.x
下载地址:https://help.sonatype.com/repomanager2/download
步骤:
cd /usr/local
mkdir nexus
tar -zxvf nexus-2.14.11-01-bundle.tar.gz -C /usr/local/nexus
检查nexus的端口号和配置
1.nexus-2.14.11-01操作页面 sonatype-work类似maven仓库
2.端口号:nexus-2.14.11-01/conf下:nexus.properties application-port=1314
3.修改系统用户为linux用户:nexus-2.14.11-01/bin/nexus脚本:RUN_AS_USER=root
4.修改防火墙暴露1314端口号
5.启动访问:bin:./nexus start
6.http://129.28.129.120:1314/nexus/#welcome
7.默认用户 admin admin123
8.仓库介绍:
group:Nexus通过管理仓库组来管理多个仓库
hostd:发布内部jar包或第三方项目架构及无法从公共仓库下载的jar包(oracle的驱动)
releases:所有非快照工程发布到这里
snapshots:存放快照模块及以SNAPSHOT结尾的工程
3rd-party:第三方依赖库,内部人员自行下载发布到此
proxy:代理仓库存储远程中央仓库的索引和构建信息
设置代理仓库:

1.修改maven配置文件

2.注释掉mirror
3.修改

4.在项目中的pom配置

5.发布快照:run build deploy

6.附件:maven的setting配置:

 | This is the configuration file for Maven. It can be specified at two levels:
 |
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in ${user.home}/.m2/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.conf}/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -gs /path/to/global/settings.xml
 |
 | The sections in this sample file are intended to give you a running start at
 | getting the most out of your Maven installation. Where appropriate, the default
 | values (values used when the setting is not specified) are provided.

   | The path to the local repository maven will use to store artifacts.

  <!-- interactiveMode
   | This will determine whether maven prompts you when it needs input. If set to false,
   | maven will use a sensible default value, perhaps based on some other setting, for
   | the parameter in question.
   |
   | Default: true
  <interactiveMode>true</interactiveMode>
  -->

  <!-- offline
   | Determines whether maven should attempt to connect to the network when executing a build.
   | This will have an effect on artifact downloads, artifact deployment, and others.
   |
   | Default: false
  <offline>false</offline>
  -->

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
   | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
   | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.

     | Specifies a further group identifier to use for plugin lookup.

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.

  <!-- servers
   | This is a list of authentication profiles, keyed by the server-id used within the system.
   | Authentication profiles can be used whenever maven must make a connection to a remote server.
   |-->
  <servers>
    <!-- server
     | Specifies the authentication information to use when connecting to a particular server, identified by
     | a unique name within the system (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
   |
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.
   |-->
  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
