Question

我试图在GWT框架中使用：http://code.google.com/p/jspf/。我知道GWT需要包含类的来源。我已将jspf的代码放在我的{SRC_DIR}中，而我的build.xml包含此条目：

 <path id="project.class.path">
    <pathelement location="${basedir}/src" />
        <fileset dir="${war_lib_dir}" includes="**/*.jar" />
    <pathelement location="${javac_precompile_classes_dir}" />
 </path>

但是当我运行ant任务时，它失败了：

[echo] Starting GWTC
    [java] Compiling module com.x.y.z
    [java]    Validating newly compiled units
    [java]       [ERROR] Errors in 'file:/u/v/XyzClass.java'

build.xml的片段

<target name="javac" depends="libs" description="Compile server java source and any other required files">
<echo>Compiling server source</echo>
<mkdir dir="${war_classes_dir}" />
<javac srcdir="${basedir}/src" includes="**/server/**/*.java" encoding="utf-8" destdir="${war_classes_dir}"
    source="1.5" target="1.5" nowarn="true" debug="true" debuglevel="lines,vars,source">

    </classpath>

GWT需要源代码，因为它将它编译为JavaScript。这些错误是因为您在应用程序的客户端使用了未在模块文件（.gwt.xml文件）中组织的源代码，或者您没有继承模块文件。这是错误引用的内容：did you forget to inherit a required module。只是添加源代码不会帮助GWT找到源代码，也必须有一个模块文件。

为了能够使用这些源，必须存在模块文件，或者您必须自己创建并在模块文件中继承它。以下是有关模块的文档：http://code.google.com/intl/nl-NL/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideModules虽然文档对于如何为这种情况创建自己的模块文件有些简要。

ANT任务包括GWT的源文件
