sbt安装与配置

下载地址：http://www.scala-sbt.org/download.html

当前版本：sbt-0.13.13.tgz

安装

1.解压并赋予权限

[root@hidden util]# tar -zxvf sbt-0.13.13.tgz
sbt-launcher-packaging-0.13.13/
sbt-launcher-packaging-0.13.13/conf/
sbt-launcher-packaging-0.13.13/conf/sbtconfig.txt
sbt-launcher-packaging-0.13.13/conf/sbtopts
sbt-launcher-packaging-0.13.13/bin/
sbt-launcher-packaging-0.13.13/bin/sbt.bat
sbt-launcher-packaging-0.13.13/bin/sbt
sbt-launcher-packaging-0.13.13/bin/sbt-launch.jar
sbt-launcher-packaging-0.13.13/bin/sbt-launch-lib.bash
[root@hidden util]# mv sbt-launcher-packaging-0.13.13 sbt
[root@hidden util]# chown -R root sbt
[root@hidden util]# chgrp -R root sbt
[root@hidden util]# cd sbt
[root@hidden sbt]# ls
bin  conf

2.建立启动脚本

在当前目录下（sbt/）创建文件sbt：vim sbt

编辑如下内容：（当前sbt的目录为：/root/util/sbt/）

#!/bin/bash
SBT_OPTS="-Xms512M -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"
java $SBT_OPTS -jar /root/util/sbt/bin/sbt-launch.jar "$@"

添加权限

[root@hidden sbt]# chmod a+x sbt

3.配置PATH环境变量

之后在/etc/profile文件中添加(vim /etc/profile)

export PATH=$PATH:/root/util/sbt/

之后将文件立即生效：

[root@hidden sbt]# source /etc/profile

1. 验证成功
   
   最后测试是否验证成功：

[root@hidden sbt]# sbt sbt-version
[info] Set current project to sbt (in build file:/root/util/sbt/)
[info] 0.13.13

异常

在实际安装过程中遇到如下的问题，在刚开始运行sbt sbt-version时出现“Error: Could not retrieve sbt 0.13.13”：

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0

这时候需要添加一点东西，首先在conf/sbtconfig.txt中添加：

[root@hidden sbt]# vim conf/sbtconfig.txt

在此文件中添加：

-Dsbt.boot.directory=/root/util/sbt/.sbt/boot
-Dsbt.global.base=/root/util/sbt/.sbt
-Dsbt.ivy.home=/root/util/sbt/.ivy2
-Dsbt.repository.config=/root/util/sbt/conf/repo.properties
-Dsbt.repository.secure=false

其次在conf/目录下添加repo.properties中添加一些内容

[root@hidden sbt]# vim conf/repo.properties

repo.properties中添加：

  Nexus osc thirdparty : https://code.lds.org/nexus/content/groups/plugin-repo/

保存。（按Esc, 输入:wq）

此时再第一次执行sbt sbt-version，效果如下：

[root@hidden sbt]# sbt sbt-version

如果出现一部分download成功一部分失败的情况，可以多试几下sbt sbt-version命令，直到只出现：

[info] Set current project to sbt (in build file:/root/util/sbt/)
[info] 0.13.13

说明安装成功。
