使用 NetBeans 时遇到错误:
Not all requested modules can be enabled: [StandardModule:org.netbeans.modules.nbjavac jarFile: C:\Users...\AppData\Roaming\NetBeans\11.2\modules\org-netbeans-modules-nbjavac.jar]
我相信这与我的问题有关，即 NetBeans 未显示 Java 提示。
该文件存在于 C:\Users\...\AppData\Roaming\NetBeans\11.2\modules\org-netbeans-modules-nbjavac.jar 中。
这是唯一被标记为错过的模块。
我知道一个常见的问题是多个模块由于错误的 JDK 路径而无法启用。我的 JDK 之路似乎是正确的:
netbeans_jdkhome="D:\Program Files\Java\jdk1.8.0_231"
如果我将其注释掉(如某些解决方案中的建议)，则提示有效，但由于 TomEE 上的多个错误，项目无法启动(在未注释的 JDK 下工作得很好):

有没有办法使用我的 JDK 并使用提示？
最佳答案
我通过在 NetBeans (11.3) 中重新安装 nb-javac 插件 (2.0) 解决了完全相同的问题
- 打开 NetBeans
- 转至工具 > 插件 > 已安装
- 启用复选框“显示详细信息”
- 搜索 javac 以找到行“The nb-javac Java 编辑支持库”
- 选择并卸载
- 重新启动 NetBeans
- NetBeans 将建议在信息框中安装 nb-javac。只需点击链接并按照说明操作即可
NetBeans 12.1 和 NetBeans 12.2 更新 这解决了错误消息“无法启用 nb-javac 插件”
关于java - 并非所有请求的模块都可以启用 - org-netbeans-modules-nbjavac.jar，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59606822/
