新手向问下，调试程序

我用的 doom emacs ，使用 lsp-java 然后在~/.doom.d/config.el 中加入了

(setq lsp-java-9-args '( "-XX:+UseParallelGC" "-XX:GCTimeRatio=4" "-XX:AdaptiveSizePolicyWeight=90" "-Dsun.zip.disableMemoryMapping=true" "-Denv=test "-Xmx8G" "-Xms1G" "-javaagent:~/.m2/m2repo/org/projectlombok/lombok/1.18.12/lombok-1.18.12.jar")) 

M-x dap-debug-edit-template 添加模板

(dap-register-debug-template "Java Run Configuration" (list :name "Debug (Launch) - Current File" :type "java" :request "launch" :args "hello" :vmArgs "-Denv=test" :jvmArgs "-Denv=test" :cwd nil :stopOnEntry :json-false :host "localhost" :request "launch" :modulePaths [] :classPaths nil :projectName "MyApp" :MainClass Hello)) 

Hello.java

 System.getProperty("env") 

M-x dap-debug ，不能获取值到 dev 的值 我想象问问是少了什么步骤吗，还是用的方法有错误？刚接触新手求教
