Question

未通过ANT生成清单文件。从它的外观来看，应该生成一个oata.HelloWorld，我假设它是Manifest File。但是，它不在build / class文件夹或build / jar文件夹中。我也在通过eclipse运行ANT

SELECT @LDate = MAX('+QUOTENAME(@DateField)+')

这是我的xml代码。

Buildfile: C:\Users\dt208672\Perforce\depot\ebill\Automation\Selenium_eBill\MarketPower\build.xml
init:
prepare:
compile:
[javac] C:\Users\dt208672\Perforce\depot\ebill\Automation\Selenium_eBill\MarketPower\build.xml:18: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds
jar:
run:
[java] Error: Could not find or load main class oata.HelloWorld
[java] Java Result: 1

你的问题与你说的完全相反。 Jar文件只有清单，如知道主类oata.HelloWorld名称的错误消息所示。

您需要将已编译的.class文件添加到Jar文件中。

<jar destfile="build/jar/HelloWorld.jar">
    <manifest>
        <attribute name="Main-Class" value="oata.HelloWorld"/>
    </manifest>
    <fileset dir="${classes.dir}" includes="**/*.class"/>
</jar>

以下对我来说很好。

SRC \ oata \ HelloWorld.java ：

package oata;
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello World");
    }
}

的build.xml ：

<project name="SeleniumProjectDataDriven" basedir="." default="run">
  <target name="init">
    <property name="src.dir" value="src" />
    <property name="build.dir" value="build" />
    <property name="classes.dir" value="${build.dir}/class" />
    <property name="jar.dir" value="${build.dir}/jar" />
  </target>

  <target name="compile" description="Compiles the code" depends="init">
    <mkdir dir="${classes.dir}" />
    <javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false" />
  </target>

  <target name="jar" description="Packages the code into jar" depends="compile">
    <mkdir dir="${jar.dir}" />
    <jar destfile="${jar.dir}/HelloWorld.jar" basedir="build/class">
      <manifest>
        <attribute name="Main-Class" value="oata.HelloWorld" />
      </manifest>
    </jar>
  </target>

  <target name="run" description="Run the jar file" depends="jar" >
    <java jar="${jar.dir}/HelloWorld.jar" fork="true" />
  </target>
</project>

输出：

compile:
Compiling 1 source file to C:\My\Workspaces\EMDRS\_test\build\class

jar:
Building jar: C:\My\Workspaces\EMDRS\_test\build\jar\HelloWorld.jar

run:
Hello World
