运行 build.xml 文件时出错

Question

我是 ANT 构建的新手，在尝试运行下面提到的构建文件时遇到了一些错误。我已经在 lib 文件夹中添加了所有 jar 文件。但我仍然面临这些错误。我想我在类路径区域犯了一些其他错误。

这里是 build.xml

<project name="ant_testing" default="compile" basedir=".">

  <property name="jar" value="${basedir}/classes"/>
  <property name="lib" value="${basedir}/lib"/>
  <property name="src" value="${basedir}/src"/>
  <property name="classes" value="${basedir}/classes"/>

  <target name="setClassPath" unless="test.classpath">
    <path id="testcompile">
      <pathelement location="${jar}"/>
      <fileset dir="${lib}">
        <include name="*.jar"/>
      </fileset>
    </path>
  </target>

  <target name="compile" depends="setClassPath">
    <javac includeantruntime="false" srcdir="${src}" destdir="${classes}" includes="**/*.java" listfiles="yes"/>
    <classpath refid="testcompile"/>
  </target>

  <target name="run" depends="compile">
    <java>
      <classpath path="classes"/>
    </java>
  </target>

</project>

这是错误列表

帮我解决这个问题 :( . 在此先感谢:)

Answer 1

你的编译在它的类路径上没有 jars。以下是您声明 javac 任务的方式：

<javac includeantruntime="false" srcdir="${src}" destdir="${classes}" includes="**/*.java" listfiles="yes"/>

尝试以下简化的构建文件：

<project name="ant_testing" default="compile" basedir=".">

  <property name="build.dir"   location="build"/>
  <property name="lib.dir"     location="lib"/>
  <property name="src.dir"     location="src"/>
  <property name="classes.dir" location="${build.dir}/classes"/>

  <path id="compile.path">
    <fileset dir="${lib.dir}" includes="*.jar"/>
  </path>

  <target name="compile">
    <mkdir dir="${classes.dir}"/>
    <javac srcdir="${src.dir}" destdir="${classes.dir}" classpathref="compile.path" includeantruntime="false"/>
  </target>

  <target name="run" depends="compile">
    <java .. ..>
      <classpath>
        <path refid="compile.path"/>
        <pathelement location="${classes.dir}"/>
      </classpath>
    </java>
  </target>
</project>

注意事项：

• 编译在顶部声明的类路径以及属性等其他项
• 属性使用“位置”属性。专为文件路径名设计
• Javac 任务使用 classpathref 来接受它的类路径
• Java 任务有一个类路径元素，由现有路径和目录文件路径元素组成。

您没有包含org.testng.annotations.BeforeTest in classpath 的罐子。只需仔细检查 jar 是否在构建阶段的类路径中（取决于您正在执行的 ant 目标）与否。我猜你的情况是${basedir}/lib
