GWTP + MGWT - jar中的錯誤：file：mgwt-1.1.1.jar！/com/googlecode/mgwt/ui/client/theme/MGWTThemeBaseThemeStandardImpl.java'

Question

我正在嘗試編寫build.xml GWTP + MGWT項目移動，桌面&平板電腦。

<javac srcdir="${apt_generated}" destdir="${out.classes.folder}" includeantruntime="true" source="1.6" target="1.6" nowarn="false" debug="true" debuglevel="lines,vars,source" > 
     <classpath refid="project.class.path" /> 
     <compilerarg value="-Xlint"/> 
    </javac> 
    <javac srcdir="${in.src.folder}" fork="true" memoryinitialsize="512m" memorymaximumsize="1024m" includes="**" encoding="utf-8" destdir="${out.classes.folder}" source="1.6" target="1.6" nowarn="false" debug="true" debuglevel="lines,vars,source" includeantruntime="true"> 
     <classpath refid="project.class.path" /> 
     <compilerarg value="-Xlint"/> 
    </javac>  
    <copy todir="${out.classes.folder}"> 
     <fileset dir="${in.src.folder}" includes="**/*.class" /> 
    </copy> 
    <delete dir="${in.src.folder}" includes="**/*.class" failonerror="false" /> 

應用程序運行在開發模式很好，但我看到下面的錯誤，當我做 「蟻族gwtc」 -

我加了fork =「true」memoryinitialsize =「512m」memorymaximumsize =「1024m」。但這些似乎並不奏效。

我在編譯GWT應用程序時遇到了一些問題，如果JRE的內存很少的話。

嘗試增加你的螞蟻進程的內存。

我的一個GWT應用程序只能在64位JVM中編譯。

我用4g RAM和64位JVM編譯我的應用程序。
