網(wǎng)上找了許多，都是oschina的源，阿里的源也試了，都很慢。最終修改源列表如下，半分鐘就好了。具體是哪一行發(fā)生了作用，就不清楚了。
~/.sbt$ cat repositories
[repositories]
local
aliyun-nexus: http://maven.aliyun.com/nexus/content/groups/public/
ibiblio-maven: http://maven.ibiblio.org/maven2/
typesafe-ivy: https://dl.bintray.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]
uk-repository: http://uk.maven.org/maven2/
jboss-repository: http://repository.jboss.org/nexus/content/groups/public/
osc: http://maven.oschina.net/content/groups/public/
typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
sonatype-oss-releases
maven-central
sonatype-oss-snapshots
測(cè)試一下，啟動(dòng)迅速，再也不用等待了。
~/.sbt$ sbt
[info] Set current project to root--sbt (in build file:/home/bit/.sbt/)

在sbt編譯spark的時(shí)候又報(bào)錯(cuò)了，連不上服務(wù)器。精簡(jiǎn)一下文件，不是越多越好，直接定位到阿里云提供的源即可。
$ dpkg -L sbt
/usr/share/sbt-launcher-packaging/conf/sbtopts
/usr/share/sbt-launcher-packaging/conf/sbtconfig.txt
這兩個(gè)文件增加一行，讓源生效：
-Dsbt.override.build.repos=true
$ cat repositories

aliyun-nexus: http://maven.aliyun.com/nexus/content/groups/public/
