You can make use of a build.xml to build the jar file for you.
您可以使用 build.xml 为您构建 jar 文件。
Then you just run the build.xml as a Ant task.
然后您只需将 build.xml 作为 Ant 任务运行。

If you want the build.xml to run automatically every time you build your Eclipse project, you can add it to the Builders list.
如果您希望每次构建 Eclipse 项目时都自动运行 build.xml，您可以将它添加到 Builders 列表中。

Below is a sample build.xml where a custom manifest is used:
以下是使用自定义清单的示例 build.xml：
<?xml version="1.0" encoding="UTF-8"?>
<project basedir="." name="Example" default="run_build">
<property name="guiJar" value="../../Library/<jar-name>.jar"></property>
<target name="run_build" depends="delete_old_jar,create_dirs,create_manifest,copy_all_class_files,create_jar,delete_temp_dirs">
</target>
<target name="delete_old_jar">
<delete file="${guiJar}">
</delete>
</target>
<target name="create_dirs">
<mkdir dir="jar_temp" />
<mkdir dir="jar_temp/META-INF" />
</target>
<target name="delete_temp_dirs">
<delete dir="jar_temp">
</delete>
</target>
<target name="create_manifest">
<manifest file="jar_temp/META-INF/MANIFEST.MF">
<attribute name="Manifest-Version" value="1.0" />
<attribute name="Version" value="1.0.0" />
<attribute name="Company" value="Value" />
<attribute name="Project" value="Value" />
<attribute name="Java-Version" value="${java.version}" />
<attribute name="Class-Path" value="test.jar" />
<attribute name="Main-Class" value="com.Main" />
</manifest>
</target>
<target name="create_jar">
<jar destfile="${guiJar}" manifest="jar_temp/META-INF/MANIFEST.MF" basedir="jar_temp">
</jar>
</target>
<target name="copy_all_class_files">
<copy todir="jar_temp">
<fileset dir="classes">
<include name="*/**" />
</fileset>
</copy>
</target>
</project>

In eclipse 3.6.1. Rigth click on your compiled project -> Export Next you should choose Java - JAR File from the tree In new form appeared after you select options don't click finish but 'Next'. Third form will be 'JAR Manifest Specification'and there you can choose your manifest file instead of eclipse generated one.
在日食 3.6.1 中。右键单击您编译的项目 -> 导出下一步，您应该从树中选择 Java - JAR 文件在您选择选项后出现的新表单中，不要单击完成而是单击“下一步”。第三种形式是“JAR Manifest Specification”，您可以在那里选择您的清单文件而不是 eclipse 生成的文件。
