如何复制文件到使用Ant的现有JAR？ [英] How do I copy files into an existing JAR with Ant?

问题描述

我有一个需要它自己的JAR文件中访问资源的项目。当我创建的JAR文件的项目，我想一个目录复制到JAR文件（我猜的ZIP相当于将增加的目录到现有的ZIP文件）。我只希望这个JAR已经创建（和我显然不希望，如果我清理并删除JAR文件发生副本）后发生的副本。

I have a project that needs to access resources within its own JAR file. When I create the JAR file for the project, I would like to copy a directory into that JAR file (I guess the ZIP equivalent would be "adding" the directory to the existing ZIP file). I only want the copy to happen after the JAR has been created (and I obviously don't want the copy to happen if I clean and delete the JAR file).

目前构建文件看起来是这样的：

Currently the build file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<project name="foobar" basedir=".." default="jar">

    <!-- project-specific properties -->
    <property name="project.path" value="my/project/dir/foobar" />

    <patternset id="project.include">
        <include name="${project.path}/**" />
    </patternset>
    <patternset id="project.jar.include">
        <include name="${project.path}/**" />
    </patternset>

    <import file="common-tasks.xml" />

    <property name="jar.file" location="${test.dir}/foobar.jar" />    
    <property name="manifest.file" location="misc/foobar.manifest" />
</project>

一些构建任务是从另一个文件（共tasks.xml），我不能在这里显示调用。

Some of the build tasks are called from another file (common-tasks.xml), which I can't display here.

推荐答案

该JAR /耳Ant任务是更普遍的邮编任务。这意味着，你也可以使用 zipfileset 在你的jar任务：

The Jar/Ear Ant tasks are subtasks of the more general Zip task. This means that you can also use zipfileset in your Jar task:

<jar destfile="${jar.file}" basedir="...">
    <zipfileset dir="${project.path}" includes="*.jar" prefix="libs"/>
</jar>

我也看到你定义一个单独的清单文件纳入到瓶子里。你也可以使用一个嵌套的清单命令：

<jar destfile="@{destfile}" basedir="@{basedir}">
    <manifest>
        <attribute name="Built-By" value="..."/>
        <attribute name="Built-Date" value="..."/>

        <attribute name="Implementation-Title" value="..."/>
        <attribute name="Implementation-Version" value="..."/>
        <attribute name="Implementation-Vendor" value="..."/>
    </manifest>
</jar>
