Come si impedisce a Maven build fail in caso di errore dell'attività Ant?

Question

Sto utilizzando la FTP Ant task con maven-antrun-plugin

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-antrun-plugin</artifactId> 
    <executions> 
     <execution> 
      <id>ftp</id> 
      <phase>generate-resources</phase> 
      <configuration> 
       <tasks> 
        <ftp action="get" 
         server="${ftp.server.ip}" 
         userid="${ftp.server.userid}" 
         password="${ftp.server.password}" 
         remotedir="${ftp.server.remotedir}" 
         depends="yes" verbose="yes" 
         skipFailedTransfers="true" 
         ignoreNoncriticalErrors="true"> 
         <fileset dir="target/test-classes/testdata"> 
          <include name="**/*.html" /> 
         </fileset> 
        </ftp> 
       </tasks> 
      </configuration> 
      <goals> 
       <goal>run</goal> 
      </goals> 
     </execution> 
    </executions> 
... 

il problema è che la mia generazione non quando la cartella $ {} ftp.server.remotedir non esiste.
Ho cercato di specificare

skipFailedTransfers="true" 
ignoreNoncriticalErrors="true 

ma questi non risolvono il problema e la costruzione mantiene fallendo.

An Ant BuildException has occured: could not change remote directory: 550 /myBadDir: The system cannot find the file specified. 

Sai come istruire il mio accumulo di Maven non si preoccupano di questo errore task Ant/o come istruire Ant per non fallire nel caso di una directory mancante?

Modifica:
La soluzione di Peter funziona.
Se un problema come

[INFO] Error configuring: org.apache.maven.plugins:maven-antrun-plugin. Reason: java.lang.NoSuchMethodError: org.apache.tools.ant.util.FileUtils.close(Ljava/io/InputStream;)V 

Basta escludere formica da ant-contrib

<dependency> 
    <groupId>ant-contrib</groupId> 
    <artifactId>ant-contrib</artifactId> 
    <version>${ant-contrib.ver}</version> 
    <exclusions> 
     <exclusion> 
      <groupId>ant</groupId> 
      <artifactId>ant</artifactId> 
     </exclusion> 
    </exclusions> 
</dependency> 

Answer 1

forse avete bisogno di pensare più come Ant e meno come Maven in questo caso.

Ecco una soluzione. Utilizzare l'attività ant-contribtrycatch. Ecco un esempio pom.xml. Copia il blocco di codice in un file denominato pom.xml ed esegui mvn validate per vederlo funzionare.

Dal Maven-antrun-plugin 1.7 è possibile aggiungere nella configurazione del tag FailOnError

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-antrun-plugin</artifactId> 
    <executions> 
     <execution> 
      <id>ftp</id> 
      <phase>generate-resources</phase> 
      <configuration> 
       <failOnError>false</failOnError> 
       <tasks> 
        <ftp action="get" 
         server="${ftp.server.ip}" 
         userid="${ftp.server.userid}" 
         password="${ftp.server.password}" 
         remotedir="${ftp.server.remotedir}" 
         depends="yes" verbose="yes" 
         skipFailedTransfers="true" 
         ignoreNoncriticalErrors="true"> 
         <fileset dir="target/test-classes/testdata"> 
          <include name="**/*.html" /> 
         </fileset> 
        </ftp> 
       </tasks> 
      </configuration> 
      <goals> 
       <goal>run</goal> 
      </goals> 
     </execution> 
    </executions> 
</plugin>
