One 、Nexus What is it?

Start using Maven when , Always hear nexus The word , For a while maven, For a while nexus, Why is it always with maven Mentioned together ？

Maven As a Excellent build tools 、 Dependency management tool 、 Project information management tools , During dependency management , adopt pom.xml Inside

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.0</version>
</dependency>

Copy

To accurately locate and find the corresponding Java Class library . In this process, we need to start from Warehouse To find the corresponding jar The package was introduced into our project , Thus, we solved the problem of Increased dependence 、 Version inconsistency 、 Version conflict 、 Rely on bloated Other questions .

Maven Yes Local repository and Remote warehouse Two kinds of , When Maven When looking for components according to coordinates , It first looks at the local warehouse , If this component exists in the local warehouse , Direct use ; If this component does not exist in the local warehouse , Or you need to see if there is an updated component version ,Maven Will go to the remote warehouse to find , After finding the required artifacts , Download it to the local warehouse and use it again .

When it comes to this , I believe you also understand ,Nexus It's a remote warehouse , It is also a kind of private service .

SNAPSHOT Snapshot version , stay maven in SNAPSHOT Version represents official release （release） Previous development version , stay pom of use x.y-SNAPSHOT Express .

RELEASE The release , Stable version , stay maven in RELEASE Represents a stable version ,unchange, Unalterable , stay maven in SNAPSHOT And RELEASE Version is a completely different way of strategy ,SNAPSHOT It will vary according to your configuration , Frequent updates from remote warehouse to local warehouse ; and RELEASE It will only be downloaded to the local warehouse for the first time , In the future, we will look directly from the local warehouse .

Two 、 Use Nexus3 build maven Private clothes

Find some references on the Internet ： Windows Use in Nexus3 build maven Private clothes maven Private clothes nexus3.x build And use Maven Private clothes Nexus3.x Environment build operation record

3、 ... and 、IDEA Package and upload to Nexus3 Private clothes

1. To configure .m2 Under the settings.xml

First , This file is on the system disk of the current device login user .m2 Under the document , Join the authentication mechanism

No, go online copy A configured one , Self configuration is easy to make mistakes

->settings.xml<-

<servers>
	<server>
	      <id>nexus</id>
	      <username>admin</username>
	      <password>admin123</password>
     </server>
     <server>
	      <id>maven-snapshots</id>
	      <username>admin</username>
	      <password>admin123</password>
     </server>
      <server>
	      <id>maven-releases</id>
	      <username>admin</username>
	      <password>admin123</password>
     </server>
     <server>
		<id>rdc-releases</id>
		<username>xxxxxxxxx</username>
		<password>xxxxx</password>
	</server>
	<server>
		<id>rdc-snapshots</id>
		<username>xxxxxxxxx</username>
		<password>xxxx</password>
	</server>
</servers>

1. To configure IDEA project Under the pom.xml

 <distributionManagement>
    <repository>
      <id>nexus</id>
      <name>nexus</name>
      <url>http://xxxx:port/repository/maven-snapshots/</url>
    </repository>

    <snapshotRepository>
      <id>maven-snapshots</id>
      <name>maven-snapshots</name>
      <url>http://xxxx:port/repository/maven-snapshots/</url>
    </snapshotRepository>
  </distributionManagement>

Copy

Here's the... In the tag id Corresponding to Article 1 server Medium id ,url The obtained value can be written directly here , It can also be shown in the figure below settings Value in file ,name You can customize ->settings.xml<-

<profile>
	<altReleaseDeploymentRepository> http://xxxx:port/repository/maven-snapshots/ </altReleaseDeploymentRepository>
	<altSnapshotDeploymentRepository> http://xxxx:port/repository/maven-snapshots/</altSnapshotDeploymentRepository>
</profile>

Copy

Again , above pom.xml Change to the following format

<distributionManagement>
    <repository>
      <id>nexus</id>
      <name>nexus</name>
      <url>${altReleaseDeploymentRepository}</url>
    </repository>

    <snapshotRepository>
      <id>maven-snapshots</id>
      <name>maven-snapshots</name>
      <url>${altSnapshotDeploymentRepository}</url>
    </snapshotRepository>
  </distributionManagement>

Copy

3. Configure the upload address , Address to private server copy

<profile> 
	<!--profile  Of  id-->
	<id>dev</id> 
	<repositories> 
		<repository> 
			<!-- Warehouse  id,repositories  Multiple warehouses can be configured , Guarantee  id  No repetition -->
			<id>nexus</id> 
			<!-- Warehouse address , namely  nexus  Address of the warehouse group -->
			<url>http://localhost:8081/nexus/content/groups/public/</url> 
			<!-- Download or not  releases  artifacts -->
			<releases> 
				<enabled>true</enabled> 
			</releases> 
			<!-- Download or not  snapshots  artifacts -->
			<snapshots> 
				<enabled>true</enabled> 
			</snapshots> 
		</repository> 
	</repositories> 
	<pluginRepositories> 
		<!--  Plug-in repository ,maven  It depends on plug-ins , Also need to download plug-ins from private server  -->
		<pluginRepository> 
			<!--  Plug in repository  id  No repetition , If you repeat the back configuration, the front edge will be overwritten  -->
			<id>central</id> 
			<name>Nexus Plugin Repository</name> 
			<url>http://central</url> 
			<releases>
               <enabled>true</enabled>
            </releases>
            <snapshots>
               <enabled>true</enabled>
            </snapshots>
		</pluginRepository> 
	</pluginRepositories> 
</profile>

Copy

4. Other configuration （ Negligible ）

For example, configure Ali's image , Map Ali central warehouse （ download jar Hurry up ）

<mirrors>
   <mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>       
  </mirror>
</mirrors>

Copy

Configure local warehouse （ No need for networking jar package ）

<localRepository>E:\maven_repository</localRepository>

Copy

5.settings.xml Full configuration （ Source network , For reference only ）

6.IDEA Package and upload

Use idea pack , Packaging will be based on pom In file version Determine whether it is a snapshot version or a release version ,version in 0.0.1-SNAPSHOT belt SNAPSHOT Is the snapshot version , Delete SNAPSHOT Release version for , Upload to private server according to version Automatically determine which warehouse to upload to

Be careful , When the packaging Project pom Make sure that the document is filled with maven-plugin Delete the , Otherwise, after the package is completed, it will generate BOOT-INF Folder , It will cause after uploading to the private server , After the dependency is configured, it can be downloaded to jar package , But no error can be found using the times package

	<version>1.1-SNAPSHOT</version>
	<build>
	
	</build>

Copy

then clean after deploy

notice BUILD SUCCESS The prompt is success , You can check on your private server
