erreur componentdef avec ant

Question

J'ai une application Grails relativement ancienne qui utilise ant pour construire l'application. Dans le serveur de test, il construit sans aucun problème, mais lorsque je tente de l'exécuter sur mon PC, je reçois une erreur cohérente:

Caused by: jar:file:/C:/ant/apache-ant-1.8.0/lib/ant.jar!/org/apache/tools/ant/antlib.xml:37: Problem: failed to create task or type componentdef 
    Cause: The name is undefined. 
    Action: Check the spelling. 
    Action: Check that any custom tasks/types have been declared. 
    Action: Check that any <presetdef>/<macrodef> declarations have taken place. 
    at org.apache.tools.ant.UnknownElement.getNotFoundException(UnknownElement.java:484) 
     at org.apache.tools.ant.UnknownElement.makeObject(UnknownElement.java:416) 
     at org.apache.tools.ant.UnknownElement.maybeConfigure(UnknownElement.java:160) 
     at org.apache.tools.ant.taskdefs.Antlib.execute(Antlib.java:146) 
     at org.apache.tools.ant.taskdefs.Definer.loadAntlib(Definer.java:432) 
     ... 63 more 

J'ai trouvé que l'erreur se produit dans la partie suivante de la construction:

<macrodef name="grails"> 
    <attribute name="script"/> 
    <attribute name="args" default="" /> 
    <sequential> 
     <grailsTask script="@{script}" args="@{args}" classpathref="grails.classpath"> 
      <compileClasspath refid="compile.classpath"/> 
      <testClasspath refid="test.classpath"/> 
      <runtimeClasspath refid="app.classpath"/> 
     </grailsTask> 
    </sequential> 
</macrodef> 

Si je commente, il n'y a plus d'erreurs.

Pour refererence plus loin, voici toute la décharge d'erreur:

Answer 1

J'ai trouvé la source du problème.

Le problème n'était pas la version de Ant, mais plutôt la version de Grails et les scripts manquants. Cette application utilisait une version obsolète de Grails (version 1.1.1).

Le code suivant, que je répertorie pour les commodités de tout le monde, appelle un script. Cependant, dans cette application particulière, avait été supprimé le script, ce qui a provoqué le processus de construction de Grails à l'accident:

<macrodef name="grails"> 
<attribute name="script"/> 
<attribute name="args" default="" /> 
<sequential> 
    <grailsTask script="@{script}" args="@{args}" classpathref="grails.classpath"> 
     <compileClasspath refid="compile.classpath"/> 
     <testClasspath refid="test.classpath"/> 
     <runtimeClasspath refid="app.classpath"/> 
    </grailsTask> 
</sequential> 
</macrodef> 

La solution était simple: mettre à niveau Grails vers une version plus récente, comme 1.3.5. La construction a fonctionné sans problèmes après cela, même si certains scripts manquaient.

Je voudrais spéculer que ce nouveau comportement a permis de générer des scripts pendant l'échafaudage, mais en même temps donner la liberté au développeur de supprimer les scripts indésirables ou inutiles.

Merci à Burth Beckwith pour ses idées.

Answer 2

Grails est pas compatible avec Ant 1.8 - vous devez utiliser 1.7.x.
