maven编译器插件的STS 3.7问题

Question

今天我下载了适用于64位机器的STS版本3.7.2。在这里，我导入了maven项目，并得到以下错误信息

Description Resource    Path    Location    Type
CoreException: Could not get the value for parameter compilerId for plugin execution default-compile: PluginResolutionException: Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.apache.maven:maven-plugin-api:jar:2.0.9, org.apache.maven:maven-artifact:jar:2.0.9, org.apache.maven:maven-core:jar:2.0.9, org.apache.maven:maven-settings:jar:2.0.9, org.apache.maven:maven-plugin-parameter-documenter:jar:2.0.9, org.apache.maven:maven-profile:jar:2.0.9, org.apache.maven:maven-model:jar:2.0.9, org.apache.maven:maven-repository-metadata:jar:2.0.9, org.apache.maven:maven-error-diagnostics:jar:2.0.9, org.apache.maven:maven-project:jar:2.0.9, org.apache.maven:maven-plugin-registry:jar:2.0.9, org.apache.maven:maven-plugin-descriptor:jar:2.0.9, org.apache.maven:maven-artifact-manager:jar:2.0.9, org.apache.maven:maven-monitor:jar:2.0.9, org.apache.maven:maven-toolchain:jar:1.0, org.codehaus.plexus:plexus-container-default:jar:1.5.5, org.codehaus.plexus:plexus-classworlds:jar:2.2.2: Failure to transfer org.apache.maven:maven-plugin-api:jar:2.0.9 from https://repo.maven.apache.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. Original error: Could not transfer artifact org.apache.maven:maven-plugin-api:jar:2.0.9 from/to central

你知道为什么这个错误吗？

Answer 1

看起来和这个one非常相似。按照链接问题的答案中的建议，尝试使用-U开关。

当然，假设STS已经正确地配置了Maven (无论是构建版本的Maven还是在您的机器上配置的Maven)。
