The cause of this is that there is an old version of ant somewhere in the |
|
|
|
class path or configuration. |

A version of this problem may be seen on some linux systems. |
|
|
|
Some linux systems (Fedora Core 2 for example), comes with a version |
|
|
|
of ant pre-installed. There is a configuration file called |
|
|
|
<code>/etc/ant.conf</code> which if present, the ant shell |
|
|
|
script will 'dot' include. On Fedora Core 2, the /etc/ant.conf |
|
|
|
file resets the <code>ANT_HOME</code> environment variable to |
|
|
|
<code>/usr/share/ant</code>. This causes the problem that |
|
|
|
an old version of ant (1.5.x in this cause) will be used |
|
|
|
with a new version of the ant script file. |

|

One can check if this is the case by doing |
|
|
|
<code>ant --noconfig -version</code>. |

Is Ant supported by my IDE/Editor? |
