Apache ant 清单类路径? [英] Apache ant manifest class-path?

问题描述

我有一个 Java 项目的标准项目布局:

I have a standard project layout for a java project:

project /
    src /
        source_file_1.java
        ...
        source_file_N.java
    build /
          classes /
              source_file_X.class
              ...
          jar /
              MyJar.jar
    lib /
          SomeLibrary.jar
          SomeOtherLibrary.jar

据我所知，我正在使用 Ant 正确构建项目.我需要在 Manifest 文件中设置 class-path 属性，以便我的类可以使用所需的库.

As far as I can tell, I am building the project correctly with Ant. I need to set the class-path attribute in the Manifest file so my classes can use the required libraries.

以下相关信息来自build.xml

The following relevant information from build.xml

<target name="compile" depends="init">
    <javac srcdir="src" destdir="build\classes">
        <classpath id="classpath">
            <fileset dir="lib">
                <include name="**/*.jar" />
            </fileset>
        </classpath>
    </javac>
</target>

<target name="jar" depends="compile">
    <jar destfile="build\jar\MyJar.jar" basedir="build\classes" >
        <manifest>
            <attribute name="Built-By" value="${user.name}" />
        </manifest>
    </jar>
</target>

任何朝正确方向的推动都值得赞赏.谢谢

Any push in the right direction is appreciated. Thanks

推荐答案

查看我的 NetBeans 生成的构建文件，我在 -do-jar-with-libraries 任务中发现了这个片段:

Looking at my NetBeans-generated build file, I found this snippet in the -do-jar-with-libraries task:

<manifest>
    <attribute name="Main-Class" value="${main.class}"/>
    <attribute name="Class-Path" value="${jar.classpath}"/>
</manifest>

换句话说，您似乎只需要向已有的清单任务添加另一个属性.

So in other words, it looks like you just need to add another attribute to the manifest task that you already have.

另请参阅清单任务文档.
