Intellij - 调试器在maven项目中不工作

我遇到了一个问题,我无法在IntelliJ中调试Maven Sprint启动REST API应用程序。应用程序启动但不会停在任何断点处。Intellij - 调试器在maven项目中不工作

此外,当我停止调试器时,我在日志中看到下面的行,但是我可以看到java进程永不终止,并且当我第二次启动应用程序时失败,因为服务器端口8080仍在使用中。

Disconnected from the target VM, address: '127.0.0.1:53020', transport: 'socket' 

Process finished with exit code -1

在C:\ Users \ Bernhard.IdeaIC2017.3 \ system \ log的IntelliJ日志中,我看到以下错误。

回答:

经过一番搜索之后,我发现问题出在IntelliJ中我的Maven Run/Debug配置。我用它来启动春季启动REST API的命令行是

clean package -Drun.profiles=dev-us-east-1 -Drun.jvmArguments=-Denvironment=dev -DskipTests spring-boot:run 

看来,-Drun.jvmArguments=-Denvironment=dev java命令行属性是罪魁祸首。当我删除它时,断点再次工作。

回答:

您可能可以用引号括住该参数的值。读取整个命令行字符串的解析器可能因为-D arg中的-D arg而窒息。

清洁套装-Drun.profiles = DEV-美国东1 -Drun.jvmArguments = “-Denvironment =开发” -DskipTests春天启动:运行
