Question

我通过 ivy 配置添加了 mvp4g 项目的 mvp4g jar 。它正确添加并在 mvp4g 的 gwt. xml 文件中提及行。但我正在尝试编译它给我的应用程序 :

Loading inherited module com.mvp4g.Mvp4gModule [ERROR] Unable to find com/mvp4g/Mvp4gModule.gwt.xml on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

请你帮我这个忙

Analysis

在挖掘 < a href=> 周围的 project homepage 后, 我发现丢失的 XML 文件实际上位于罐头文件中 :

unzip -t ./Mvp4g_Layout_Part2/war/WEB-INF/lib/mvp4g-1.4.0.jar | grep xml
testing: com/mvp4g/Mvp4gModule.gwt.xml   OK
testing: META-INF/maven/com.googlecode.mvp4g/mvp4g/pom.xml   OK

意思是说,虽然它可能是用常春藤下载的,但不会出现在您的编译类路径上。

Assumption

您没有具体说明您是如何使用罐子的, 所以我必须假设上述错误是 ANT < 坚固 > javac < /坚固 > 的任务所丢弃的。

Example

ivy.xml

d 我宣布常春藤依赖性,并将其与汇编组合相联系如下:

<ivy-module version="2.0">
    <info organisation="com.myspotontheweb" module="demo"/>

    <configurations>
        <conf name="compile" description="Required to compile application"/>
    </configurations>

    <dependencies>
        <dependency org="com.googlecode.mvp4g" name="mvp4g" rev="1.4.0" conf="compile->default"/>
    </dependencies>

</ivy-module>

build.xml

在 ANT 文件 Id 使用 Ivy cachepath 的任务来创建 ivy 管理的 ANT 路径。

<target name="init">
    <ivy:resolve/>

    <ivy:report todir= ${ivy.reports.dir}  graph= false  xml= false />

    <ivy:cachepath pathid="compile.path" conf="compile"/>
</target>

此路径在 < 坚固 > javac < / 坚固 > 任务( 或任何其他能够接受类路径引用的 ANT 任务) 中作为正常使用。

<target name="compile" depends="init">
    <javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false" debug="true" classpathref="compile.path"/>
</target>
