我尝试从我的代码创建exe文件，但它让我犯了错误
java.lang.ClassNotFoundException: Access2
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
at java.security.AccessController.doPrivileged(Native Method)
我使用exe4j工具从jar文件生成exe
我用了Jdk 1.8.0_25
这是我的主要课程（Access2）的一部分

我该如何解决？它说我的班级没找到，但它存在什么解决方案？
答案 0 :(得分：1)
这是因为类文件的包装不当，或者是包内不正确的Java文件编译。
使用包含Java文件的干净目录来获取Maven等构建工具，然后生成.jar。
基本上，如果可以的话，创建一个新的Maven或Ant项目并创建具有相同名称的Java文件，并将内容逐个粘贴到新文件中。
编辑：确保主包中只有一个公共类。
