EclipseLink 2：ANT 任务错误

Question

我得到了这个 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>

当我运行上述任务时，我得到了这个错误：

我已将错误跟踪到这一行

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

对于上述错误有解决方法吗？

Answer 1

为了解决错误java.net.URISyntaxException：索引 2 处不透明部分中的非法字符，我必须将 META-INF 移动到 ANT 的 build.xml 所在的同一目录。这只是一个解决方法。

我已在 https://bugs.eclipse.org/bugs/show_bug 记录了一个错误.cgi?id=345808。 EclipseLink 人员已在 EclipseLink 版本 2.3.0 版本中修复了此错误。
