scala - 无法使用 :cp command 将 jar 添加到 Scala repl

Question

如果我发出:

$ scala -classpath poi-3.9/poi-3.9-20121203.jar 

scala> import org.apache.poi.hssf.usermodel.HSSFSheet
import org.apache.poi.hssf.usermodel.HSSFSheet

一切正常，但如果我发出:

$ scala

scala> :cp poi-3.9/poi-3.9-20121203.jar
Added '/home/sas/tmp/poi/poi-3.9/poi-3.9-20121203.jar'.  Your new classpath is:
".:/home/sas/tmp/poi/poi-3.9/poi-3.9-20121203.jar"
Nothing to replay.

scala> import org.apache.poi.hssf.usermodel.HSSFSheet
<console>:7: error: object apache is not a member of package org
       import org.apache.poi.hssf.usermodel.HSSFSheet
                  ^

我错过了什么吗？

Answer 1

似乎没有人提到这一点，但正确的解决方案是使用 :require command :

scala> :require foo.jar
Added 'foo.jar' to classpath.
