导入包编译成jar:类文件错误，类文件包含错误的类和包不存在错误

Question

我已经创建了一个包，并使用ant将其编译成一个jar文件。

文件结构是这样的

project folder
  x_package
    compiled package_x.jar
    com
      name
        package_x
          Package files
  demos
    src
      files I'm trying to compile

我正在尝试编译demo/src下的文件，这些文件依赖于已编译的package_x.jar

我通过将package_x.jar作为javac任务

的参数添加到类路径来实现这一点<<p> Javac任务/strong>

    <javac destdir = "${build.dir}" source = "${ant.java.version}" target = "${ant.java.version}" 
        debug = "true" deprecation = "false" optimize = "false" failonerror = "true" >
        <src path = "${source.dir}" />
        <classpath refid = "master-classpath"/>
    </javac>

master-classpath

    <path id = "master-classpath" > 
        <fileset dir = "${classpath.dir}" >
            <include name = "*.jar" />
        </fileset>
        <pathelement path = "${classpath.dir}" />
    </path>

每当我运行ant文件时，就会出现2个错误

error: package package_x does not exist

和在第一次引用包

中定义的类时

error: Cannot access class_name
bad class file C:/(path)/package_x.jar (class_name)
class file contains wrong class: package_x.class_name
please remove or make sure it appears in the correct subdirectory of the classpath

在package_x包中，每个文件都以

开头

package package_x;
/*code*/

和demos目录下的文件有

import package_x.*;
/*code*/

欢迎指教

我不确定这是否是唯一的问题，但在包声明和导入中，您必须编写完整的包路径，如com.name.package_x
