今天新建一個springboot項目時,項目建好后,在IDEA下載依賴包時,下載了很久都沒有下載完,后來仔細一看,是下載不了。
解決方法:
在項目的pom.xml文件上右鍵,彈出框中選擇maven,再選擇open 'settings.xml' 或者是 create 'settings.xml' ,操作如圖:
在該文件中填入如下內容:
<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <mirrors> <mirror> <id>nexus</id> <name>internal nexus repository</name> <!-- <url>http://192.168.1.100:8081/nexus/content/groups/public/</url>--> <url>http://repo.maven.apache.org/maven2</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> </settings>
重新右鍵pom.xml文件,選擇 maven ,選擇 Reimport 即可下載依賴。操作步驟及settings.xml文件內容如圖:
settings.xml文件內容:
至此,依賴依法下載的問題已經解決。。
疑惑:將settings.xml文件中的<mirrors>替換成如下內容,竟然也無法下載依賴(但看網上博客說會讓下載速度變快的)
<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.
