maven的settings.xml里設置為阿里云私服 mirror部分替換如下

<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>

-->

<mirror>

<id>nexus-aliyun</id>

<mirrorOf>*</mirrorOf>

<name>Nexus aliyun</name>

<url>http://maven.aliyun.com/nexus/content/groups/public</url>

</mirror>

</mirrors>

你好，我的也報這個錯，后來我把jdk1.7.0_80 ?換成了jdk1.8.0_152， 再重新運行，就成功了。

都兩天了，還沒有解決呢

有人回答嗎？我的也是這個錯誤。。。

這個不用你手動下載，你把pom寫好了，在這里mvn compile 第一次運行它會自己下些東西的
