Question

我正在尝试使用maven构建一个java spring项目（默认项目来自heroku入门-guide）。因为我不断得到以下错误。机器在访问互联网时不应该有任何问题。

Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test 
(default-test) on project spring-hibernate-template: 
Execution default-test of goal org.apache.maven.plugins:maven-surefire-    
plugin:2.12.4:test failed: 
Plugin org.apache.maven.plugins:maven-surefire-plugin:2.12.4 or one of its 
dependencies could not be resolved: 
Cannot access central (http://repo.maven.apache.org/maven2) in offline mode and
the artifact org.codehaus.plexus:plexus-utils:jar:1.1 has not been downloaded 
from it before.

我的pom文件，以防有任何帮助。

Answer 1

错误消息显示为in offline mode。

如果您没有在命令行中使用-o或--offline构建，那么settings.xml文件中可能存在<offline/>元素。

或者，如果您正在构建这种方式，也可以通过IDE应用此设置。

Maven构建失败并显示错误消息插件org.apache.maven.plugins：maven-surefire-plugin：2.12.4或其某个依赖项无法解析
