的EclipseLink 2：ANT任务错误

Question

我得到这个Ant任务：

<javac verbose="on" 
    srcdir="${src.dir}" 
    destdir="${build.dir}/${context.path}/classes" 
    debug="${compile.debug}" 
    debuglevel="${javac.debuglevel}" 
    optimize="${compile.optimize}" 
    deprecation="${javac.deprecation}" 
    failonerror="true"> 
    <compilerarg value="-Aeclipselink.persistencexml=${web.dir}/META-INF" compiler="javac1.6" /> 
    <compilerarg line=" -processor org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor" /> 
    <compilerarg line=" -proc:only" compiler="javac1.6" /> 
    <classpath refid="compile.classpath"/> 
</javac> 

当我运行上面的任务，我得到这个错误：

我跟踪误差这一行<compilerarg value="-Aeclipselink.persistencexml=${web.dir}/META-INF" compiler="javac1.6" />。它看起来像解析器不喜欢编译器的参数值-Aeclipselink.persistencexml。上述错误对于JDK 1.6.0.24和JDK 1.6.0.25都是可重现的。该错误是由org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor.process造成的。

我使用的是与Glassfish 3.1捆绑在一起的EclipseLink版本2.2.0.v20110202-r8913。我也尝试使用独立的EclipseLink库2.2.0.v20110202-r8913编译上述任务，并得到相同的错误。

是否有解决上述错误的方法？

Answer 1

要解决错误java.net.URISyntaxException: Illegal character in opaque part at index 2，我不得不将我的META-INF移动到ANT的build.xml所在的同一个目录中。这只是一个解决方法。

我已经在https://bugs.eclipse.org/bugs/show_bug.cgi?id=345808注册了一个bug。 EclipseLink人员修复了EclipseLink 2.3.0版本的这个错误。
