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
