Tenho as seguintes instruções no meu build.xml e estou recebendo a seguinte exceçã

launch4j: net.sf.launch4j.ExecException: Exec falhou (1): C: \ Arquivos de programas \ Launch4j \ bin \ windres.exe - pré-processador = tipo -J rc -O coff -F pe-i386 C: \ Windows \ TEMP \ launch4j2603642297702639520rc C: \ Windows \ TEMP \ launch4j1179691608441365102o

Este é o meu script de construção:

Alguém pode me ajudar a descobrir o que estou fazendo de errado?
