 |

I spent some hours trying to get latest (2.13) JSwat to emerge. Finally, i discovered what needs to be done before "emerge jswat". In case someone else needs new version of JSwat, here's a little tutorial. Also, this might solve some ant and junit problems.
First we ofcourse need java - because JSwat is a Java debugger :) To use JSwat 2.x, you need 1.4.x jdk, eg. sun-jdk-1.4.1.01. There is a 1.4.1-beta version of Blackdown JDK, but i haven't tested it.
To install Sun's JDK-1.4.x, do
Building JSwat needs ant (for actual building. for you who didn't know, "Apache Ant is a Java-based build tool. In theory, it is kind of like Make, but without Make's wrinkles.") and JUnit (used for some tests during the build process, i guess).
Lets start with getting the latest (masked!) ant and junit (I heard people have had some problems with older versions).
| Code: |
ACCEPT_KEYWORDS="~x86" emerge ant junit
|
Now that we have ant (and junit) installed, we need to add $ANT_HOME to our profile. Also, to use junit, we need to modifiy the $CLASSPATH. So, edit /etc/env.d/java/20JDKNAME file (/etc/env.d/java/20sun-jdk-1.4.1.01 in my system)
Add this:
| Code: |
ANT_HOME="/usr/share/ant"
|
And append ANT_HOME to ENV_VARS and junit.jar to CLASSPATH
| Code: |
CLASSPATH=/opt/sun-jdk-1.4.1.01/jre/lib/rt.jar:/usr/share/junit/lib/junit.jar:.
ENV_VARS="JAVA_HOME CLASSPATH JDK_HOME JAVAC ADDPATH ADDLDPATH ANT_HOME"
|
Now run java-config --set-system-vm=... (or --set-user-vm). In this case, that would be
| Code: |
java-config --set-system-vm=sun-jdk-1.4.1.01
|
This generates /etc/env.d/20java file (that is why we don't want to edit it directly; it is generated by java-config)
Then, lets update the environment
| Code: |
env-update && source /etc/profile
|
Now, take a break. Go drink some coffee, go out for a smoke or something. Eat cookies ;)
Ok, then to the emerge process. First, make your local portage dir and set it as PORTDIR_OVERLAY in make.conf (if you haven't already done so). For example,
| Code: |
PORTDIR_OVERLAY=/usr/home/sibbe/portage
|
This way your own ebuilds are not deleted during emerge rsync.
Next step is to get an ebuild file for the latest JSwat. I found couple from bugs.gentoo.org for version 2.11. Close enough, so just changed the version. Grab ebuild-file here.

S="${WORKDIR}/jswat-2.13"
DESCRIPTION="Extensible graphical Java debugger"
HOMEPAGE="http://www.bluemarsh.com/java/jswat"
SRC_URI="http://cesnet.dl.sourceforge.net/sourceforge/jswat/jswat-src-2.13.tar.gz"
LICENSE="GPL-2"
SLOT="2"
KEYWORDS="*"
DEPEND=">=dev-java/ant-1.4.1"
#this next line should be changed to >=virtual/jdk once we have a bunch of 1.4 JDK's
RDEPEND=">=virtual/jdk-1.4"
src_compile() {
echo $S
# we cannot use jikes here because we would get
# a java.lang.VerifyError from the ClassLoader (why?)
echo "2.13" | ant || die "compile problem"
}
src_install () {
# install it as new CLASSPATH package because other programs
# (like app-editors/jedit) can make use of it
cd build/dist/jswat-2.13
dojar jswat.jar parser.jar jclasslib.jar
cd ../../..
echo -e >jswat '#!/bin/sh\njava -classpath /usr/share/jswat/lib/jswat.jar:$JDK_HOME/lib/tools.jar com.bluemarsh.jswat.Main $@'
chmod 755 jswat
dobin jswat
dodoc AUTHORS.txt BUGS.txt HISTORY.txt LICENSE.txt OLD_HISTORY.txt TODO.txt
dohtml README.html
dohtml -r docs
}
|
Final steps; cd to local portage dir, make directory for jswat, put ebuild there, build digest file for it and finally emerge jswat:
| Code: |
mkdir -p dev-java/jswat
wget http://www.kruu.org/jvtm/files/jswat-2.13.ebuild
ebuild /usr/home/sibbe/portage/dev-java/jswat/jswat-2.13.ebuild digest
emerge jswat
|
Now you should have JSwat 2.13 installed.
And to use your new and fresh Java debugger, check out the docs at http://www.bluemarsh.com/java/jswat/docs/index.html
edit: oh, and it might be wise to add "junit" to your make.conf's USE variables..
