[gutsy] No ant support

[Edmundo]

I can't get to have eclipse to use an ant file.

here's the log output:

Eclipse 3.2 requires ant 1.6. However, gutsy only includes ant 1.7. The solution is to either install eclipse 3.3(?) or install ant 1.6 and change the ant home directory from eclipse-> Window-> Preferences-> Ant.

[Rogelio Castillo A. (rogelio2k)]

Ant don't work

[Kevin McGuinness (kevin-mcguinness)]

Installing ant 1.6.5 and setting eclipse-> Window-> Preferences-> Ant ->Ant Home to the new path does not work.
Indeed, you shouldn't need to do this at all, considering that by default eclipse points Ant Home to it's internal
version of ant (1.6.5) in /usr/lib/eclipse/plugins.

[Kevin McGuinness (kevin-mcguinness)]

The other workaround (install eclipse 3.3) does appear to work, however

[sircam (sircam)]

The ANT 1.6 workaround with Eclipse 3.2 + Sun Java6 did not work for me. Stumbled accross AntLauch ClassNotFound exception, although I had change ANT_HOME in Eclipse.

However, installing 3.3 Europa seems to be a good move. It's fairly easy (although not automated, download & unzip and you're rolling), ANT 1.7 works fine, plus you get the latest features.

[Mikael Nilsson (mini)]

This is a really annoying eclipse bug. Has this been traced at all? There should be a simple workaround (with the existing 3.2 installation)

[Richard Andreu (randreu)]

Same problem here, I've installed Eclipse 3.3 manually and it works fine. Installing Ant 1.6.5 and pointing Ant Home to that installation path doesn't work in Eclipse 3.2.

[sandos (sandos)]

Argh, so no solution to this problem then? :(

I can't really use eclipse 3.3 due to an important plugin not working for it (P4WSAD) so 3.3 does not help me.

[Mikael Nilsson (mini)]

I've worked around the problem by doing this:

cd /tmp
mkdir ant
cd ant
unzip /usr/share/java/ant-launcher.jar
unzip /usr/share/java/ant.jar
jar cf ../ant.jar *
sudo rm /usr/lib/eclipse/plugins/org.apache.ant_1.6.5/lib/ant-launcher.jar
sudo rm /usr/lib/eclipse/plugins/org.apache.ant_1.6.5/lib/ant.jar
sudo cp ../ant.jar /usr/lib/eclipse/plugins/org.apache.ant_1.6.5/lib/ant.jar

(requires unzip and a working jar executable).

Plus ça change, plus c'est la même chose

[Eden Crane (ubuntulaunchpad-tonecontrol)]

I am using sun-java6-jre and I also encountered this bug. The fix from Mikael Nilsson worked for me but I agree, it is very annoying. Many Java developers who use Eclipse use Ant and would like this to work 'out of the box'.

[naut (naut)]

Mikael's workaround does not work for me, unfortunately.

This is a serious bug. Ant is the de facto standard build tool for Java. Eclipse is the most popular IDE for Java developers [ http://www.zefhemel.com/archives/2003/10/18/java-ide-market-share-survey ]. And Java is the most popular application programming language [ http://www.tiobe.com/index.html?tiobe_index ] in the world today!

For the integration between these tools to be so completely broken is a huge bug. I can't believe Henrik Nilsen Omma has declined this for gutsy gibbon, I just hope he reconsiders.

[Sami Mäkinen (sami-makinen-helsinki)]

I would also like to request that this be fixed now in Gutsy, rather than waiting for the next version with its new issues.

For me, as a Java developer using Bluetooth a lot, Gutsy seems to have a lot of things broken that used to work before. Not the best version, this one.

[Pierrick Vandenbroucke (vanpie)]

I also encountered the same problem with Ant and Eclipse, but I have a temporary solution: I use Ant in the terminal (after sudo apt-get install ant).

[toxic (gaiduri)]

the problem is that the eclipse ant plugin's jar files are linked to those in /usr/share, that is the v1.7.0.3 version of ant. this is the case in 8.04 beta, and although the ant version is different, was also the case in 7.10.

my solution was to put ant 1.6.5 somewhere, rename the plugins lib directory, and link to the lib directory of the 1.6.5 version. note that as far as i can tell all the scripts, etc. are not aliased, only the jar files are, so this should be the only change required. i performed this myself a short while ago, being fed up with not seeing my projects targets in the dialog box, and now all seems to be well.

[todor (todor-gitchev)]

I've experienced the same problem and have tried all the tips above but no success. I'm running Kubuntu 8.04 x64 bits on and the provided Eclipse 3.2.2. I was playing around with the provided ANT eclipse plug-in org.apache.ant_1.7.0.v200706080842 and the separate provided ANT 1.7.0 but with no success so far. I also find this problem a bit sever as these two tools are the most important for me now as Java development environment.
I'll be thankful for every tip to overcome this issue.
Thanks in advance.

[Sami Mäkinen (sami-makinen-helsinki)]

Well, right now on Kubuntu Hardy 64bit ant seems to work via eclipse.

eclipse is 3.2.2-5ubu
ant is 1.7.0-3

Perhaps this bug could be closed as fixed then? Is somebody still seeing problems?

[toxic (gaiduri)]

hi

i can assure you that this works.

besides, as has been suggested, there are other workarounds. you can run it
from the command line. as such it is an annoyance, but not particularly a
product flaw (i should know, i work in development support).

Hi...

The eclipse-cpp (Eclipse IDE for C/C++ developers) distribution has a broken ANT support at least since the Europa release.

Symptom: In Eclipse, under Window->Preferences, there is no category "Ant".

Diagnosis: only the the plugin "org.eclipse.ant.core" is provided. "org.eclipse.ant.ui" is missing.
I had this both on Linux (Debian) and Windows after installing eclipse-cpp.

Solution:
- Don't use the eclipse-cpp distribution. Take the "Eclipse Classic" distribution from http://www.eclipse.org/downloads/ instead and install the C/C++ support manually. Then you will have both C/C++ and a working ANT.

- if you don't want to replace your existing installation, you can still download the "classic" distribution (just 151MB ;-), and extract the JARs missing in the "cpp" distribution from there (version numbers apply to the current Ganymede release):

eclipse/plugins/org.eclipse.ant.ui_3.3.0.v20080529.jar
eclipse/plugins/org.eclipse.jdt.core_3.4.2.v_883_R34x.jar
eclipse/plugins/org.eclipse.jdt.debug.ui_3.3.1.v20080730_r341.jar
eclipse/plugins/org.eclipse.jdt.launching_3.4.1.v20080729_r341.jar
eclipse/plugins/org.eclipse.jdt.core.manipulation_1.2.0.v20080603-2000.jar
and the following directory
eclipse/plugins/org.eclipse.jdt.debug_3.4.0.v20080604/

The first JAR is what's obviously missing, and the others are it's dependencies.

Hope that helps for all those who had to say "does not work for me".

Cheers,
Adrian
