ANNOUNCE: A New Version of NetBeans Scala Plugins with sbt Interagtion.

[Caoyuan]

I would like to announce the availability of a new version of NetBeans Scala plugins.

This version contains a new developed sbt integration and varies bug fixes.

It requires NetBeans 7.1+ and Scala 2.10.x

For more information:
https://github.com/dcaoyuan/nbscala/wiki/SbtIntegrationInNetBeans

For downloading:
https://sourceforge.net/projects/erlybird/files/nb-scala/7.x_2.10.x/

Does it support sbt projects that defines subprojects?

Yes. The subprojects (aggregate or dependencies) will be organized as it. And if you've had these projects compiled, you can clicking jump between these projects' sources.

You may want to take a look at a snapshot at:

I'm getting this in the sbt console:

 SBT -Completion: <tab> -Exit: exit -Help: help.  sbt.home=null

netbeans

[info] Loading project definition from /home/rcano/Development/luthier/project

[info] Set current project to Luthier (in build file:/home/rcano/Development/luthier/)

[error] Expected '/'

[error] Expected ':'

[error] Not a valid key: netbeans (similar: test, tags, streams)

[error] netbeans

And the project is not being picked up :(

[Caoyuan]

Have you tried the steps described in :
https://github.com/dcaoyuan/nbscala/wiki/SbtIntegrationInNetBeans

[Rodrigo Cano]

Oh, sorry, I've been following your development on https://github.com/dcaoyuan/nbscala, and compiling via maven, and generating the .nbm with mvn clean install nbm:autoupdate. I'm going to try that. Thanks.

[Rodrigo Cano]

By the way, in that wiki page you linked, it states that you must add the plugin:

addSbtPlugin("org.netbeans.sbt" % "sbt-plugin" % "1.0.0")

when actually, the plugin published locally after running 

sbt compile publish-local

on

git clone g...@github.com:dcaoyuan/nbsbt.git

is org.netbeans.nbsbt % nbsbt-plugin.

[Rodrigo Cano]

Its working now!, thanks.

You still can't delete breakpoints by clicking on them in the LHS editor
gutter.

Really? This version should have fixed it.

Just tried it, it sets them OK but won't delete them, you need to use
the Breakpoints window. In case the uninstall of the old version wasn't
clean I'll try uninstalling the new modules and clearing any remnants
out by hand, then reinstalling. Do you have a list of candidate files I
should make sure are gone, cached stuff etc?

1. Uninstall all modules under category "scala"

2. check the netbeans user directory place from NetBeansInstallation/etc/netbeans.conf，delete the 'var' directory under this place.

That seems to have fixed that problem but I'm getting an exception
during startup:

Do you run the REPL from within Netbeans?

[Caoyuan]

Which REPL console did you open? The on from NetBeans' menu bar, or a console from a sbt console? If it's the previous one,  I think it's a bug.

BTW, I can run console within NetBeans' sbt console.

No, that's from the command line but your comment about running the REPL
from inside NetBeans gave me a clue where to go looking. If I try doing
that I get the following message:

SCALA_HOME environment variable may not be set or is invalid, Please set
SCALA_HOME first.

I'm running this from a Gnome shortcut to the NetBeans executable and
although my shell environment has SCALA_HOME set, it isn't getting set
if I invoke NetBeans from the Gnome shortcut. If I manually start
NetBeans from a shell prompt it works fine - no exception on startup and
the debugger works, so it's clearly the lack of SCALA_HOME in the
environment that is the problem.

For previous versions of the Scala plugin I've added
"-J-Dscala.home=/opt/scala" to the "netbeans_default_options" property
in $NBHOME/etc/netbeans.conf and that's done the trick, doesn't that
work any more?

With SCALA_HOME set, viewing the Scala Platform Manager says I have
Scala 1.1 running which looks like a bug and I have the following
Platform Classpath, does that look correct? I notice there's no
scala-reflect.jar in there.

For previous version, the environment variable SCALA_HOME will be set automatically to java property 'scala.home', but I dropped this feature in this released version. I do not think it's a good idea to do much hidden things :-)

I'm not using SBT so I don't think it is that.

Which is a problem for people launching NetBeans from a desktop link or
Window Manager menu, such as the ones that the standard NetBeans
installer sets up. Much of the existing documentation for the Netbeans
Scala plugin mentions setting this option in netbeans.conf and I didn't
see anything in the release notes to say it no longer worked. I think
removing it was a mistake.

I'll re-think about it.

Even with SCALA_HOME set I get a slew of errors to stdout if I run
NetBeans from a shell:
