包含在 build.xml 中的 JAR 文件不会按声明的顺序在类路径中获取

Question

这是我的构建.xml文件。我已经按照我需要的特定顺序包含了jar文件(这很重要。如果没有，我会得到包裹是密封的例外(。但是我得到的类路径是：

[echo] Classpath is C:Usersaswathy_krishnaneclipse-workspaceMerckDemolibiwats-scripting-library-v1.9.jar;C:Usersaswathy_krishnaneclipse-workspaceMerckDemolibjcommander-1.27.jar;C:Usersaswathy_krishnaneclipse-workspaceMerckDemolibjson-20160810.jar;C:Usersaswathy_krishnaneclipse-workspaceMerckDemolibtessract-wrapper.jar;C:Usersaswathy_krishnaneclipse-workspaceMerckDemolibtestng-6.11.jar

我做错了什么？如何确保我的 tesseract 包装纸始终是第一个要包含的罐子？我是蚂蚁的初学者。

我尝试通过testNG运行测试，它工作正常。这是因为我按顺序优先处理我的 tesseract jar 和构建路径的导出选项卡。请帮忙。

fileset

不会导致有序集合。要对类路径定义中的元素进行排序，应改用多个<pathelement ...>：

<path id="build.classpath">
<pathelement location="${lib}/tessract-wrapper.jar"/>
<pathelement location="${lib}/testng-6.11.jar"/>
<pathelement location="${lib}/iwats-scripting-library-v1.9.jar"/>
<pathelement location="${lib}/json-20160810.jar"/>
<pathelement location="${lib}/jcommander-1.27.jar"/>
</path>
