Question

我无法使用Ant通过终端编译源代码，因为尽管我发出了'ant resolve或ant retrieve'，但依赖关系似乎无法正确解析？

我的build.xml和下面的ivy.xml

的build.xml

<!-- ANT HOME ENVIRONMENT VARIABLE -->
<property name="ant.home" value="${env.ANT_HOME}" />

<!-- IVY HOME DIRECTORY -->
<property name="ivy.home" value="${ant.home}" />

<!-- IVY2 JAR DIRECTORY (REPOSITORY) -->
<property name="ivy.default.ivy.user.dir" value="${user.home}/.ivy2"/>

<!-- DOWNLOAD IVY -->
<target name="setup" description="Install ivy">
    <mkdir dir="${user.home}/.ivy2" />
    <get dest="${ivy.home}/lib/ivy.jar" src="http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.3.0/ivy-2.3.0.jar"/>
</target>

<!-- RESOLVE CLASSPATHS -->
<target name="resolve" description="Use ivy to resolve classpaths">
    <ivy:resolve file="ivy.xml" />
    <ivy:report todir='target/ivy-reports' graph='false' xml='false'/>
    <ivy:cachepath pathid="ivy.path" conf="compile" />
</target>

<!-- RETRIEVE DEPENDANCIES AFTER RESOLVING-->
<target name="retrieve" depends="resolve" description="Use ivy to retrieve dependencies">
    <ivy:retrieve sync="true" type="jar" />
</target>

<!-- COMPILE PROJECT -->
<target name="compile" depends="clean, retrieve">
    <!-- Create build directory -->
    <mkdir dir="target/${ant.project.name}" />

    <!-- Compile source code -->
    <javac includeantruntime="false" srcdir="src" debug="true" destdir="target/${ant.project.name}" >
        <classpath>
            <path refid="ivy.path" />
        </classpath>
    </javac>
</target>

<!-- CLEAN TARGET DIRECTORY -->
<target name="clean">
    <delete dir="target/orderlycalls" />
    <delete dir="target/classes" />
    <delete dir="target/ivy-reports" />     
</target>

<!-- CLEAN TARGET AND IVY CATCHE -->
<target name="clean-all" depends="clean" description="Additionally purge ivy cache">
    <ivy:cleancache/>
</target>

的ivy.xml

<ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">

    <configurations>
        <conf name="default" visibility="public" description="The single built artifact. Nothing else"/>
        <conf name="compile" visibility="public" description="The master module and transitive dependencies"/>
        <conf name="provided" visibility="public" description="Needed for compile. Will be provided outside or war"/>
        <conf name="runtime" visibility="public" description="Not required for compile, but for runtime" extends="compile"/>
        <conf name="default" visibility="public" description="The default configuration" extends="runtime"/>
        <conf name="test" visibility="private" description="Required for testing" extends="runtime"/>
    </configurations>

    <dependencies>
        <dependency org="net.sf.trove4j" name="trove4j" rev="3.0.3" conf="provided"/>
        <dependency org="org.apache.tomcat.embed" name="tomcat-embed-core" rev="7.0.53" conf="provided"/>
    </dependencies>

</ivy-module>

当我运行'ant compile'时，on编译ant抱怨它无法找到'Servlet Context'，它是tomcat.jar或'TObject'的一部分，'THashMap'是trove.jar的一部分，还有更多尽管我正在检索/解析build.xml中的jar。

我注意到的另一件事是我的.ivy2 / cache //里面没有实际的jar文件。只有xml文件

知道我做错了什么或根本不做什么？

您已使用cachepath任务创建Ant路径，使用与＆＃34; compile＆＃34;相关联的依赖项。组态。

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

您的问题在于您的常春藤文件，您没有通过映射到＆＃34;编译＆＃34;来指定任何依赖项。组态。这可以解释为什么你的javac任务看不到任何罐子。

   <configurations>
        ...
        <conf name="compile" .../>
        <conf name="provided" .../>
        ...
    </configurations>

    <dependencies>
        <dependency ... conf="provided"/>
        <dependency ... conf="provided"/>
    </dependencies>

我建议为每个配置创建一个显式映射，例如：

<!-- Compile dependencies --> 
<dependency org="net.sf.trove4j" name="trove4j" rev="3.0.3" conf="compile->default"/>

<!-- provided dependencies -->
<dependency org="org.apache.tomcat.embed" name="tomcat-embed-core" rev="7.0.53" conf="provided->master"/>

您唯一需要的映射是以下远程配置：

默认远程jar及其传递依赖
master 仅限远程jar
