java - 构建开放式NMS时出错

Question

我有 openNMS 1.8.12-1 源代码，并尝试使用 maven 构建它，并将项目导入 eclipse 进行开发。我已经在命令行中运行了命令 mvn eclipse:clean eclipse:eclipse -e 。我收到的构建错误为

org.apache.maven.lifecycle.LifecycleExecutionException: Unable to write to file:

右键单击这些文件夹

D:\Software\NMS\opennms-1.8.12-1\source\core\api\.settings\org.eclipse.jdt.c ore.prefs 

在操作系统级别的属性中，查看是否选中了只读，需要取消选中。尝试创建一个文本文件，看看是否可以保存任何内容。如果它有效，请查看我的评论旁边的这些向上箭头，请确保单击它们；)
