deploy上傳到私服配置注意事項(踩坑經驗)


deploy時報錯Deployment failed: repository element was not specified i n the POM inside distributionManagement

  • 是因為項目pom.xml里沒有,如下配置
  <distributionManagement>
 
        <repository>
            <id>xxx</id>
            <name>xxx</name>
            <url>http://mxxx/nexus/content/repositories/releases/</url>
        </repository>
  
    </distributionManagement>
  • 還需要maven的settings.xml加上私服的配置,貼上我自己的配置,可以對照下。

	| | 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.home}/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

		store artifacts. | | Default: ~/.m2/repository <localRepository>/path/to/local/repo</localRepository> -->

	<localRepository>D:/mavenRepository</localRepository>

	<!-- interactiveMode | This will determine whether maven prompts you when

		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

		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

	<!-- 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. | <server>

	<!-- 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> 
			<id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable 
			Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url> 
			</mirror> -->
	</mirrors>

	<!-- profiles | This is a list of profiles which can be activated in a variety 
		of ways, and which can modify | the build process. Profiles provided in the 
		settings.xml are intended to provide local machine- | specific paths and 
		repository locations which allow the build to work in the local environment. 
		| | For example, if you have an integration testing plugin - like cactus 
		- that needs to know where | your Tomcat instance is installed, you can provide 
		a variable here such that the variable is | dereferenced during the build 
		process to configure the cactus plugin. | | As noted above, profiles can 
		be activated in a variety of ways. One way - the activeProfiles | section 
		of this document (settings.xml) - will be discussed later. Another way essentially 
		| relies on the detection of a system property, either matching a particular 
		value for the property, | or merely testing its existence. Profiles can also 
		be activated by JDK version prefix, where a | value of '1.4' might activate 
		a profile when the build is executed on a JDK version of '1.4.2_07'. | Finally, 
		the list of active profiles can be specified directly from the command line. 
		| | NOTE: For profiles defined in the settings.xml, you are restricted to 
		specifying only artifact | repositories, plugin repositories, and free-form 
		properties to be used as configuration | variables for plugins in the POM. 
		| | -->
	<profiles>
		<!-- profile | Specifies a set of introductions to the build process, to 
			be activated using one or more of the | mechanisms described above. For inheritance 
			purposes, and to activate profiles via <activatedProfiles/> | or the command 
			line, profiles have to have an ID that is unique. | | An encouraged best 
			practice for profile identification is to use a consistent naming convention 
			| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 
			'user-brett', etc. | This will make it more intuitive to understand what 
			the set of introduced profiles is attempting | to accomplish, particularly 
			when you only have a list of profile id's for debug. | | This profile example 
			uses the JDK version to trigger activation, and provides a JDK-specific repo. 
			<profile> <id>jdk-1.4</id> <activation> <jdk>1.4</jdk> </activation> <repositories> 
			<repository> <id>jdk14</id> <name>Repository for JDK 1.4 builds</name> <url>http://www.myhost.com/maven/jdk14</url> 
			<layout>default</layout> <snapshotPolicy>always</snapshotPolicy> </repository> 
			</repositories> </profile> -->

		<!-- | Here is another profile, activated by the system property 'target-env' 
			with a value of 'dev', | which provides a specific path to the Tomcat instance. 
			To use this, your plugin configuration | might hypothetically look like: 
			| | ... | <plugin> | <groupId>org.myco.myplugins</groupId> | <artifactId>myplugin</artifactId> 
			| | <configuration> | <tomcatLocation>${tomcatPath}</tomcatLocation> | </configuration> 
			| </plugin> | ... | | NOTE: If you just wanted to inject this configuration 
			whenever someone set 'target-env' to | anything, you could just leave off 
			the <value/> inside the activation-property. | <profile> <id>env-dev</id> 
			<activation> <property> <name>target-env</name> <value>dev</value> </property>

源碼中寫死的中文亂碼

  • 像這樣的,msg是代碼里寫死的。
    在這里插入圖片描述

在這里插入圖片描述

  • 解決方案<encoding>utf-8</encoding>,主要是這句。
  <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>utf-8</encoding>
                </configuration>
            </plugin>

上傳的jar包要能打開source,需要加上下面的插件

 <!-- 要將源碼放上去,需要加入這個插件 -->
            <plugin>
                <artifactId>maven-source-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <attach>true</attach>
                </configuration>
                <executions>
                    <execution>
                        <phase>compile</phase>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

排除某些模塊不要上傳到私服

  • 比如我的需求是api模塊是公用的,只上傳api模塊和父模塊就可以了,那么在其他源碼模塊的pom.xml增加如下配置。
		 <!--不要deploy上傳到私服-->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-deploy-plugin</artifactId>
                <version>2.8.2</version>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>

拉取的jar不是最新的

  • 我們deploy上傳jar包后,會發現新其他機器拉取的jar包不是最新的。這是因為本地倉庫有這個jar,所以沒有再拉取;這也和更新策略有關系。
解決辦法:
  • 第一種:刪除本地倉庫的jar,重新拉取。
  • 第二種:deploy前修改版本號,用到這個jar包的地方也改下版本號,相當於每次上傳都是新的jar,引用的地方用最新的版本。
