This seems to be the problem described in <a href="https://bugzilla.redhat.com/show_bug.cgi?id=490542" rel="nofollow noreferrer">Bug 490542</a> (that applies to Fedora 12 too according to the last comment). Sadly, the bug is still in a NEW state so I don't think it will be solved in a near future.

Regarding ANT_HOME, doesn't <code>/etc/ant.conf</code> set it to <code>/usr/share/ant</code> as explained <a href="http://ant.apache.org/faq.html#InstantiationException" rel="nofollow noreferrer">here</a>? This may be outdated but I can't check it (and I don't really get how this should be setup on Fedora).

blocks|key|1242625|text|我对maven-ant-tasks.jar也有同样的问题。Ant在类路径中显示了jar文件，但没有在标记中找到它。ANT_HOME的改变对我没有用，但我找到了另一个解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1242626|可选的jar文件必须在/etc/ant.d中的一个简单文本文件中注册，其中包含jar文件的名称(或路径)，其中路径相对于/usr/share/java，并且没有扩展名".jar“。|1242627|因此，如果您想注册maven-ant-任务，那么只需将maven-ant-tasks.jar+(或它的符号链接)放到/usr/share/java中，并将文件"+maven-ant-tasks“添加到/etc/ant.d，其中包含行："maven-ant-tasks”。|1242628|这至少在openSuse+11.1上适用于我。也许这对某人有帮助。|1242629|汉尼斯|1242630|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I just had the same problem with maven-ant-tasks.jar. Ant showed the jar file in the classpath but didn't find it in the tag. The change of ANT_HOME didn't work for me, but I found another solution:

The optional jar files have to be registered in a simple text file in /etc/ant.d containing the name (or path) of the jar file, where the path is relative to /usr/share/java and without the extension ".jar".

So if you want to register maven-ant-tasks for example, then simply put maven-ant-tasks.jar (or it's symlink) into /usr/share/java and add the file "maven-ant-tasks" to /etc/ant.d consisting of the line: "maven-ant-tasks".

That works at least for me on openSuse 11.1. Maybe this helps somebody.

I get same issue on centos 7 google cloud build-in ant is 1.9.x
I try to download newest ant 1.10.x but have same issue

Setting <code>ANT_HOME</code> to <code>/usr/share/ant/</code> also resolve it.

Configuration: I'm running stock Fedora 12 with the ant that Fedora ships:

<ul>
<li>ant-1.7.1-12.fc12</li>
<li>java-1.6.0-openjdk-1.6.0.0-33.b16.fc12</li>
</ul>

I have <code>svnant.jar</code> and <code>svnClientAdapter.jar</code> in my <code>$HOME/.ant/lib/</code>

I'm using the following <code>build.xml</code>:

<pre><code>&lt;project name="antlibtest" default="doEcho"&gt;
 &lt;taskdef resource="svntask.properties"/&gt;

 &lt;target name="doEcho"&gt;
 &lt;echo message="Hello World!"/&gt;
 &lt;echo message="ANT_HOME=${ant.home}"/&gt;
 &lt;echo message="classpath=${java.class.path}"/&gt;
 &lt;/target&gt;
&lt;/project&gt;
</code></pre>

When the build file is executed, I get the following error:
[taskdef] Could not load definitions from resource svntask.properties. It could not be found.

If I set ANT_HOME to <code>/usr/share/ant/</code> it works flawlessly.

In both cases, the jars from my home directory are clearly in the output of the classpath.

How do I make this work without resorting to my own copy of ant, ANT_HOME and ant --noconfig?

Why does ant ignore task jars in $HOME/.ant/lib/
