當(dāng)使用mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app來(lái)創(chuàng)建一個(gè)新項(xiàng)目時(shí)，有時(shí)候會(huì)出現(xiàn)以下錯(cuò)誤：

請(qǐng)注意紅色部分為錯(cuò)誤產(chǎn)生的根本原因，
由于maven
還處于開(kāi)發(fā)過(guò)程中，開(kāi)發(fā)方極有可能已經(jīng)更新某個(gè)plug-in
的版本，但本地plug-in
的metadata
沒(méi)有版本的信息或者沒(méi)有最新版本的信息，致使maven
無(wú)法下載正確的版本。同時(shí)請(qǐng)注意藍(lán)色部分，這是提示的解決辦法。具體步驟如下：
1.打開(kāi)網(wǎng)址：http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/maven/archetypes/maven-archetype-quickstart/
2.選擇最新版本并且下載最新的“maven-archetype-quickstart-1.0-alpha-4.jar ”文件
3.安裝這個(gè)archetype到maven本地倉(cāng)庫(kù)。使用命令如下：mvn install:install-file -DgroupId=org.apache.maven.archtypes -Dar
tifactId=maven-archetype-quickstart -Dversion=1.0-alpha-4 -Dpackaging=jar -Dfile=c:\7000\maven\maven-archetype-quickstart-1.0-alpha-4.jar。注意-Dfile是剛下載的文件的路徑。
現(xiàn)在在cmd中執(zhí)行mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app就可以創(chuàng)建新項(xiàng)目了。
