我的项目之一的构建开始失败,下面给出了例外情况

   > Could not resolve org.slf4j:slf4j-api:[1.6.1,).
  > Failed to list versions for org.slf4j:slf4j-api.
     > Unable to load Maven meta-data from https://repo1.maven.org/maven2/org/slf4j/slf4j-api/maven-metadata.xml.
        > Could not GET 'https://repo1.maven.org/maven2/org/slf4j/slf4j-api/maven-metadata.xml'.
           > Received fatal alert: protocol_version

环境:

• Java 7
• Gradle 3.5

我们计划将应用程序的 Grails 从版本 2.0.1 升级到 3.1.1。执行时

    grails clean --stacktrace --verbose    

我收到以下异常：

   | Error Error occurred running Grails CLI: null
     java.lang.NullPointerException
    at org.grails.cli.GrailsCli.initializeProfile(GrailsCli.groovy:504)
    at org.grails.cli.GrailsCli.initializeApplication(GrailsCli.groovy:308)
    at org.grails.cli.GrailsCli.execute(GrailsCli.groovy:271)
    at org.grails.cli.GrailsCli.main(GrailsCli.groovy:162)
  | Error Error occurred running Grails CLI: null

我也尝试过设置，GRAIL_OPTS但仍然不起作用。

   set GRAILS_OPTS="-XX:-UseSplitVerifier -Xverify:none"

环境详情：

    | Grails Version: 3.1.1
    | Groovy Version: 2.4.5
    | JVM Version: 1.8.0_74

任何指示将不胜感激。

谢谢。
