maven 手動添加jar包到本地倉庫，及處理報錯Failed to transfer file: http://repo.maven.apache.org/maven2/org/springf...

在Jenkins中構建項目，遇到maven缺乏插件的問題：spring

[ERROR] Failed to execute goal on project mianshi-service: Could not resolve dependencies for project com.shiku:mianshi-service:jar:0.0.1-SNAPSHOT: The following artifacts could not be resolved: com.xiaomi.push:mipush-sdk-server:jar:2.2.18, org.json:json-simple:jar:1.1.1: Could not find artifact com.xiaomi.push:mipush-sdk-server:jar:2.2.18 in spring-snapshots (http://repo.spring.io/snapshot) -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

方法一：apache

有時maven庫中的插件很差拉取，如網速很差或特殊的項目依賴包等因素，能夠將須要的jar包直接添加到本地maven庫中，減小不少麻煩。json

一、準備好須要的jar包，放置在方便的路徑下，並進入到這個目錄vim

二、執行命令：mvn install:install-file -Dfile=json-simple-1.1.1.jar -DgroupId=org.json -DartifactId=json-simple -Dversion=1.1.1 -Dpackaging=jar服務器

須要什麼包就改爲相應的名字，執行後將出現下面提示，以後構建就不會出現maven缺包的狀況：maven

方法二：spring-boot

,我今天遇到這個狀況，方法一不起效，在本機上直接執行構建命令就能夠構建成功，可是在Jenkins上構建，仍是報上面的錯誤，檢查了Jenkins的配置，項目配置，沒有發現任何問題，無奈之下，只有設置Jenkins的全局變量設置，將maven改爲自動安裝：系統管理-->全局工具配置-->maven工具

而後打開項目配置，在pre step中添加mvn的添加插件到倉庫的命令，須要注意的是，要在服務器的相應目錄中準備好jar包，配置保存後，構建項目就不會出現maven缺乏包的問題了。ui

（我構建以前是將服務器上的maven卸載了的，Jenkins在構建項目時，會下載maven這個插件，而後在Jenkins的目錄下保存maven的倉庫，那卸不卸載本機的maven，看你本身的了）url

設置maven倉庫地址

最近遇到一個問題，在編譯程序時，在 Parsing POMs時報錯，錯誤以下：

ERROR: Failed to parse POMs
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.1.0.RELEASE from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.0.RELEASE from/to central (http://repo.maven.apache.org/maven2): Failed to transfer file: http://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.1.0.RELEASE/spring-boot-starter-parent-2.1.0.RELEASE.pom. Return code is: 501 , ReasonPhrase:HTTPS Required. and 'parent.relativePath' points at wrong local POM @ line 12, column 13

這個錯誤提示咱們，在 http://repo.maven.apache.org/maven2中找不到咱們要的資源，我翻了全部關於maven的配置文件，沒發現倉庫配有這個地址，那算了，從新配置一個鏡像

編輯maven的配置文件settings.xml,具體位置在哪，根據安裝路徑找一下 find / -name settings.xml

vim settings.xml

在mirrors中添加一下配置

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

如圖：

以後從新編譯項目就行了
