java - 带有外部 jar 的 Java 构建文件

转载作者：太空宇宙更新时间：2023-11-04 08:09:53

我已经尝试并再次尝试为我的项目大纲开发一个 Ant Buildfile:

NoClassDefFoundError when running Java from Windows command line with external jar files

这是我尝试运行的 Buildfile:

<project>

 <target name="clean">
 <delete dir="build" />
 </target>

 <path id="jarpath">
 <fileset dir="C:\JAR">
 <include name="**" />
 </fileset>
 </path>

 <target name="compile">
 <mkdir dir="build/classes" />
 <javac srcdir="." destdir="build/classes" includeantruntime="false">
 <classpath id="jarpath" />
 <classpath>
 <pathelement path="jarpath" />
 </classpath>
 </javac>
 </target>

 <target name="jar">
 <mkdir dir="build/jar" />
 <jar destfile="build/jar/TestCase1.jar" basedir="build/classes">
 <manifest>
 <attribute name="Main-Class" value="NSSR.TestCase1" />
 </manifest>
 </jar>
 <jar destfile="build/jar/UniversalVariables.jar" basedir="build/classes">
 <manifest>
 <attribute name="Main-Class" value="NSSR.UniversalVariables" />
 </manifest>
 </jar>
 </target>

</project>

当我在 Windows 的命令行中输入“ant compile”时，它给了我这个庞然大物的错误:

基本上，它似乎无法识别我的 jar 文件中的任何内容，我认为这是有道理的，因为我没有在编译目标中引用它们。问题是我不知道如何引用它们(这是我除了 Hello World 之外的第一个 Buildfile)。

谢谢

最佳答案

您遇到的问题是设置和管理类路径。这是迄今为止 ANT 构建中最常见的问题...

当我查看您的代码时，您似乎应该运行 junit ...

我整理了一个修改后的构建文件，演示了以下内容:

用途 apache ivy管理所有 3rd 方 jar 依赖项

使用 Ant 运行 junit 测试 junit task

打包一个完整的带有类路径的可执行 jar

希望能帮助到你。

例子

该项目是从以下问题中提供的源代码构建的:

NoClassDefFoundError when running Java from Windows command line with external jar files

|-- build.xml
`-- src
    `-- NSSR
        |-- TestCase1.java
        `-- UniversalVariables.java

您需要运行以下目标一次才能安装 ivy plugin

ant bootstrap

然后按如下方式运行构建

ant clean jar

然后可以按如下方式执行生成的 jar；

java -jar build/dist/demo.jar
