我使用以下maven命令
创建了一个新的maven项目mvn archetype:generate -DgroupId=com.company.lib_name -DartifactId=lib_name -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
当我在eclipse中打开这个新创建的项目时,会出现以下错误:
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar- plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-jar-plugin:jar:2.3.2
Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-jar-plugin:jar:2.3.2: Hostname cannot be null
我尝试了以下内容:
知道什么'主机名不能为空'指着?

您似乎已经从Maven模板创建了项目,但在Eclipse中导入之前您没有将此项目作为Eclipse项目。
因此,在使用maven命令创建新的maven项目之后,您还应该执行以下命令将项目作为Eclipse项目
mvn eclipse:eclipse
它将生成Eclipse IDE所需的所有项目文件。
我还希望在Eclipse中导入项目之前执行&#34; mvn clean install&#34; 。

在命令提示符处
日食:日食 mvn clean install这应该下载所有依赖项

谢谢大家的答案。但问题出在maven repo网址上。
