I have jar archive build with Ant 1.9.1 When I launch class from it I get the following exception:

Caused by Java exception: java.lang.NoSuchMethodError: com.gargoylesoftware.htmlunit.html.HtmlCheckBoxInput.setChecked(Z)V

        at com.blablabla.kats.Main.main(Main.java:158)

When I compile "com.blablabla.kats.drivers.CheckBox" class by javac and replace corresponding file in jar all works fine. I use htmlunit 2.12

java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

corresponding Ant task:

<path id="classpath.libraries">
    <fileset dir="${basedir}/lib">
      <include name="*.jar"/>
    </fileset>
  </path>


     <target name="compile">
        <javac srcdir="${basedir}/src/java" destdir="classes"  debug="true" source="1.5" target="1.5">
          <classpath refid="classpath.libraries" />
        </javac>
      </target>

${basedir}/lib contains a lot of jars.
The main are kats.jar - my project, containing com.blablabla.kats.drivers.CheckBox
htmlunit-2.12.jar - where com.gargoylesoftware.htmlunit.html.HtmlCheckBoxInput.setChecked(Z) is.

Why it can happen?

我发现我没有删除旧的编译类。当我清理编译的类时一切正常。

我看到的唯一区别是，您在 ant 脚本中使用 1.5，而查看您使用 java6 运行它的 java 版本。我不确定这是否会产生很大的不同，因为它应该向后兼容，但仍然试一试。在 ant build.xml 中将此版本更改为 1.6
