运行 grail App 时出现以下错误。我已经尝试了各种方法，但错误并没有消失。

任何人都可以请帮忙。

`Server access Error: Connection refused url=http://grails.org/plugins/grails-mysql-connector-java/tags/RELEASE_5_1_16/mysql-connector-java-5.1.16.pom`

请检查您的"grails-app/conf/BuildConfig.groovy"

我想你可能会不小心编辑它。看起来 msql-connector 放置在错误的位置。

dependencies {
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.
    runtime 'mysql:mysql-connector-java:5.1.16'  // RIGHT PLACE
}

plugins {
    runtime ":hibernate:$grailsVersion"
    runtime ":jquery:1.7.1"
    runtime ":resources:1.1.5"

    build ":tomcat:$grailsVersion"
    //runtime ':mysql-connector-java:5.1.16' // WRONG PLACE, IF YOU SAW HERE.
}

我发现我需要为 grails 设置代理
