每个项目的SBT调试端口

如何基于每个项目更改SBT调试端口?

我可以将调试JVM选项添加到环境变量SBT_OPTS

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005

但这将适用于所有SBT实例,如果我想同时在两个单独项目的调试中运行SBT,我会收到此错误,因为该端口已在使用中:

ERROR: transport error 202: bind failed: Address already in use

通过自制软件修改sbt附带的sbt脚本,我创建了这个脚本,让你启动sbt并指定调试端口,如下所示:

sbt-debug 5005

#!/bin/sh
test -f ~/.sbtconfig && . ~/.sbtconfig

SBT_LAUNCH=/usr/local/Cellar/sbt/0.12.1/libexec/sbt-launch.jar
# Take leading integer as debug port and not sbt args
DEBUG_PORT=$1
SBT_ARGS=`echo "$@" | grep -oE "[^0-9].*"`

exec java -Xmx512M -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=${DEBUG_PORT} ${SBT_OPTS} -jar $SBT_LAUNCH $SBT_ARGS
