Java 无法在创建maven项目时计算生成计划

我刚刚创建了一个新的maven项目，在创建时，我已经有一个错误：

Description Resource    Path    Location    Type
CoreException: Could not calculate build plan: Plugin org.apache.maven.plugins:maven-compiler-plugin:2.3.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:2.3.2: ArtifactResolutionException: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:2.3.2 from/to central (http://repo.maven.apache.org/maven2): null to http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-compiler-plugin/2.3.2/maven-compiler-plugin-2.3.2.pom pom.xml /WD_Automation  line 1  Maven Project Build Lifecycle Mapping Problem

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile (execution: default-testCompile, phase: test-compile) pom.xml /WD_Automation  line 1  Maven Project Build Lifecycle Mapping Problem

我不明白为什么，因为我没有碰过pom中的任何东西或其他任何东西

你有什么想法吗？

Maven试图从MavenCentral下载插件，但失败了。这通常是网络或代理问题。

从错误消息中，可能是该存储库

http://repo.maven.apache.org/maven2

未为您访问，您可以在internet上搜索可用的存储库。

我用Eclipse光子4.8.0的java8补丁替换了Eclipse开普勒4.3.2 SR2，问题已经解决。

如果我无法更改网络或代理，是否有解决方案？您可以将代理配置放入设置中。xml您有没有示例？代理/防火墙问题。。。
