Latest ant in Fedora 14 is 1.7 but I need ant 1.8

So I run the Android SDK on my Fedora 14 PC. Before yesterday I had everything working - Ant 1.7, Eclipse 3.6.1 (Helios), and I was building my Android apps no problem.

Then I went into eclipse and installed updates. Now I'm running a newer Android SDK and it requires a later version of Ant (1.8). The latest version of ant available in Fedora 14 is Ant 1.7. I don't see a way to get back to the old sdk.

So as far as I can tell, what I ne开发者_如何学Goed to do is remove Ant 1.7 and then manually install Ant 1.8 (and all the dependencies that go with it, see below).

If I just re-installed everything, I would end up in the same place because the Android SDK would still require Ant 1.8 and Fedora would still only offer Ant 1.7.

Has anybody else encountered or solved this problem yet? Any advice?

The hfollowing snippet shows the output of a yum remove command, which shows all the dependencies of ant which I would have to manually install:

You can take newest ant package from ant rpm package
Get all rpm needed and after install it with yum.
Something like:
$ wget -r -A.rpm k -nc -l1 -e robots=off http://kojipkgs.fedoraproject.org/packages/ant/1.8.2/3.fc15/noarch/
$ su -c ' yum --nogpgcheck install $(find kojipkgs.fedoraproject.org/ -name "*.rpm") '

One good alternative for this on Fedora 14 is use rawhide repos and just install / update ant simply with yum. I answered your question more detailed here.

Perhaps you could try setting Ant Home... property in Eclipse -> Window -> Preferences -> Ant -> Runtime to the ant 1.8 that you have installed.

I'd previously built Android APKs with Ant 1.8.2 but only from the command line, never in Eclipse. I'm letting it import the main_rules.xml from the Android SDK, so that all the Proguard targets get included automatically. I'm running Windows not Linux and have Ant in my path.

I thought I'd see if it can be built using the Eclipse plugin. I've had success doing the following:

1) As Raghuram suggested, set the Eclipse Ant preference runtime to the folder where your 1.8 is. If you try and build an Android build.xml (imported into Eclipse) it will fail saying that it can't find the the Ant setup task.

2) I then added the AndroidSDK/tools/lib/antasks.jar into the Global entries for the classpath under the Eclipse/Preferences/Ant/Runtime preferences. The Ant view in Eclipse still says it can't find the classpath, but I ignore it and select the target and run it. It builds just fine. The only snag is that the Ant view doesn't tell me what particular build.xml it is. That might be because I don't have the project name in my build.xmls, as I have it in the build.properties file, so that I can use the same build.xml fro different projects.
