我在windows nanoserver上暴露了SGW_HOME变量，并试图在xml文件中使用它

<service>

  <!-- ID of the service. It should be unique across the Windows system-->
  <id>SGWJavaService</id>
  <name>SGWJavaService</name>
  <description>SGW Java service</description>
  <env name="SGW_HOME" value="%SGW_HOME%"/>
  <!-- Path to the executable, which should be started -->
  <!-- CAUTION: Don't put arguments here. Use <arguments> instead. -->
  <executable>java</executable>
  <arguments>-jar %SGW_HOME%\\lib\\mgmt-node-1.0.0.jar</arguments>
</service>

我可以用命令创建服务

WinSW-x64.exe install sgw.xml

但服务无法启动

C:\program-files>sc query SGWJavaService

SERVICE_NAME: SGWJavaService
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 1  STOPPED
        WIN32_EXIT_CODE    : 1067  (0x42b)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

C:\program-files>

我如何使用env变量到xml文件？
