Apparently in the meantime my internet connection crashed.

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project comicsTest: Could not resolve dependencies for project comicsTest:comicsTest:war:0.0.1-SNAPSHOT: The following artifacts could not be resolved: org.springframework:spring-context:jar:3.0.5.RELEASE, org.hibernate:hibernate-entitymanager:jar:3.6.0.Final, org.hibernate:hibernate-core:jar:3.6.0.Final, org.hibernate:hibernate-commons-annotations:jar:3.2.0.Final, org.aspectj:aspectjweaver:jar:1.6.8, commons-lang:commons-lang:jar:2.5,

(org.apache.maven.lifecycle.LifecycleExecutionException：无法在项目comics上执行目标Test：无法解决项目comics的依赖项Test：comicsTest：war：0.0.1-SNAPSHOT：无法解决以下工件：org.springframework：spring- context：jar：3.0.5.RELEASE，org.hibernate：hibernate-entitymanager：jar：3.6.0.Final，org.hibernate：hibernate-core：jar：3.6.0.Final，org.hibernate：hibernate-commons-批注：jar：3.2.0.Final，org.aspectj：aspectjweaver：jar：1.6.8，commons-lang：commons-lang：jar：2.5，)

mysql:mysql-connector-java:jar:5.1.13: Failure to transfer org.springframework:spring-context:jar:3.0.5.RELEASE from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.

(mysql：mysql-connector-java：jar：5.1.13：无法从本地存储库中缓存来自http://repo1.maven.org/maven2的 org.springframework：spring-context：jar：3.0.5.RELEASE传输，直到Central的更新间隔或强制进行更新后，才会重新尝试解析。)

Original error: Could not transfer artifact org.springframework:spring-context:jar:3.0.5.RELEASE from central ( http://repo1.maven.org/maven2 ): No response received after 60000

(原始错误：无法从中央（ http://repo1.maven.org/maven2 ）传输工件org.springframework：spring-context：jar：3.0.5.RELEASE：60000之后未收到响应)

And I have no idea how to force maven to update?

(而且我不知道如何强制Maven更新？)

  ask by M4ks translate from so

Answer 1

mvn clean install -U

-U means force update of snapshot dependencies.

(-U表示强制更新快照依赖项。)

Release dependencies can't be updated this way.

(发布依赖项无法通过这种方式进行更新。)
