的EclipseLink 2：ANT任務錯誤

Question

我得到這個Ant任務：

<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> 

當我運行上面的任務，我得到這個錯誤：

我跟蹤誤差這一行<compilerarg value="-Aeclipselink.persistencexml=${web.dir}/META-INF" compiler="javac1.6" />。它看起來像解析器不喜歡編譯器的參數值-Aeclipselink.persistencexml。上述錯誤對於JDK 1.6.0.24和JDK 1.6.0.25都是可重現的。該錯誤是由org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor.process造成的。

我使用的是與Glassfish 3.1捆綁在一起的EclipseLink版本2.2.0.v20110202-r8913。我也嘗試使用獨立的EclipseLink庫2.2.0.v20110202-r8913編譯上述任務，並得到相同的錯誤。

是否有解決上述錯誤的方法？

Answer 1

要解決錯誤java.net.URISyntaxException: Illegal character in opaque part at index 2，我不得不將我的META-INF移動到ANT的build.xml所在的同一個目錄中。這只是一個解決方法。

我已經在https://bugs.eclipse.org/bugs/show_bug.cgi?id=345808註冊了一個bug。 EclipseLink人員修復了EclipseLink 2.3.0版本的這個錯誤。
