ant dosyasıyla ilgili yardım - Java görev için classpath görev

Question

Aşağıdaki antivirüs dosyası Ant'e sahip ve programı çalıştırmak için 'run' hedefini kullanmaya çalışıyorum. Aynı classpathref kullanma

<property name="springjar" location="E:/Tools/spring-30/dist/" /> 
<property name="logjar"  location="E:/Tools/commons-logging-1.1.1/" /> 

<patternset id="jar.files"><include name="**/*.jar"/></patternset> 

<path id="springlearn.classpath"> 
    <fileset dir="${springjar}"><patternset refid="jar.files"/></fileset> 
    <fileset dir="${logjar}"><patternset refid="jar.files"/></fileset> 
</path> 


<target name="run" depends="dist" description="Execute the Java Program"> 
    <java dir ="." fork="true" jar="dist\app.jar" classpathref ="springlearn.classpath"> 
    </java> 
</target> 

, başarıyla kavanoz oluşturmak & derlemek mümkün, ama hedef koşmak kullandığınızda, ben

"ana" nın altında hatayı dizisindeki

java.lang.NoClassDefFoundError: org/springframework/core/io/Resource

İstisna olsun

java task docs Gönderen:

kavanoz özelliğini kullanmak, tüm sınıf yolu ayarları Sun's specification göre göz ardı edilir.

Kurduğunuz sınıf yoluna hiç bakılmıyor.

Sen Sınıfyoluna dist/app.jar eklemek ve doğrudan ana sınıf diyebiliriz: Eğer kavanozu aramak isterseniz

<java dir ="." fork="true" classname="com.yourdomain.YourMainClass"> 
    <classpath> 
    <path refid="springlearn.classpath" /> 
    <pathelement location="dist\app.jar" /> 
    </classpath> 
</java> 

varsayılırsa, oluştururken manifest'teki sınıf yolu girişi kurmak gerekir . pathconvert görevine bir göz atın, bu yararlı olabilir.
