網(wǎng)上找了許多，都是oschina的源，阿里的源也試了酵熙，都很慢。最終修改源列表如下揖膜，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

aliyun-nexus: http://maven.aliyun.com/nexus/content/groups/public/
ibiblio-maven: http://maven.ibiblio.org/maven2/

測試一下临梗，啟動迅速涡扼，再也不用等待了稼跳。
~/.sbt$ sbt

在sbt編譯spark的時(shí)候又報(bào)錯(cuò)了，連不上服務(wù)器吃沪。精簡一下文件汤善，不是越多越好，直接定位到阿里云提供的源即可票彪。
$ dpkg -L sbt
/usr/share/sbt-launcher-packaging/conf/sbtopts
/usr/share/sbt-launcher-packaging/conf/sbtconfig.txt
這兩個(gè)文件增加一行红淡，讓源生效：
-Dsbt.override.build.repos=true
$ cat repositories
