Problemi ANT: net/sf/antcontrib/antcontrib.properties

Question

Sto tentando di installare il software sul mio server Debian Lenny. In particolare, Capture-HPC. Ho installato il server VMWare, insieme a tutti i prerequisiti. Quando vado a eseguire ant nella directory, ottengo il seguente errore:

[taskdef] Could not load definitions from resource net/sf/antcontrib/antcontrib.properties. It could not be found. 

Qualcuno ha qualche idea che cosa sta causando questo? I dettagli sulla mia installazione di formica seguono:

Apache Ant version 1.7.0 compiled on April 29 2008 
Buildfile: build.xml 
Detected Java version: 1.6 in: /usr/lib/jvm/java-6-sun-1.6.0.20/jre

E il file build.xml. . .

Answer 1

Questo messaggio di errore indica che si sta tentando di caricare un compito non-core, ma la risorsa che definisce ulteriormente il compito non è presente (o non dove previsto).

Vedere le istruzioni di installazione here.

È possibile sia

1. find/scaricare il vaso ant-contrib e metterlo nella propria installazione ant (come per l'opzione 1 nel link qui sotto); oppure
2. Modifica il tuo file ant (come per l'opzione 2 nel link sopra) per includere il jar ant-contrib in un classpath nidificato.
