java.lang.SecurityException：禁止的包名称：java.lang

Question

尝试构建非常简单的Web服务项目时出现以下错误。 我已经给出了build.xml，我的java文件和路径值

正在生成类文件，但未生成服务。

请帮忙。。。

谢谢！ :)

Answer 1

您自己的课程在哪个包中？

发生此错误是因为禁止将自己的类放入包java.lang 。 看起来您正在尝试编译java.lang包中的类。

如果您自己的类根本不在包中（源文件顶部没有package语句），则将它们放在包中。

Answer 2

如果确保您的项目包名称不是以Java或javax开头，请尝试使用以下方式：

当我跑步时：

mvn clean install     

CLI中的命令，它显示构建成功，当我使用Eclipse编译项目时，它显示

java.lang.SecurityException：禁止的软件包名称：java.lang.annotation

但是我的parnter项目是正确的，我认为这是IDE或编译环境问题，当我将jdk版本从1.8x降级到1.7x时，问题就消失了。
