Gradle 使用动态参数列表执行命令行

Question

我们有一个可以在本地或远程服务器上运行的应用程序。在本地运行时，需要设置代理，因为应用程序使用云上的另一项服务。
这样做是这样的:

commandLine "java", "-Xmx227m",
        "-Dapplication.name=showcase-rest",
        "-Dserver.port=$applicationPort",
        "-Dspring.profiles.active=$springActiveProfiles",
        "-Didm.realm=develop",
        "-Dhttp.proxyHost=10.xx.xxx.129", "-Dhttp.proxyPort=3xxx",
        "-Dhttps.proxyHost=10.xx.xxx.129", "-Dhttps.proxyPort=3xxx",
        "-Dhttp.nonProxyHosts=localhost|127.0.0.1",
        "-jar", tasks.jar.destinationDir.toString() + "/showcase-rest-SNAPSHOT.jar"

但是，当在云上的适当服务器上运行时，我们不需要代理设置:

commandLine "java", "-Xmx227m",
        "-Dapplication.name=showcase-rest",
        "-Dserver.port=$applicationPort",
        "-Dspring.profiles.active=$springActiveProfiles",
        "-Didm.realm=develop",
        "-jar", tasks.jar.destinationDir.toString() + "/showcase-rest-SNAPSHOT.jar"

怎么可能做到这一点？

我知道如何向 gradle 提供和解析 jvm 参数；问题是如何在 commandLine 中“注入(inject)”这些代理设置动态的。

到目前为止，我尝试过:

    def proxyConfig = ["-Dhttp.proxyHost=10.xx.xxx.129", "-Dhttp.proxyPort=3xxx",
                       "-Dhttps.proxyHost=10.xx.xxx.129", "-Dhttps.proxyPort=3xxx",
                               "-Dhttp.nonProxyHosts=localhost|127.0.0.1"] as List<String>
commandLine "java", "-Xmx227m",
        "-Dapplication.name=showcase-rest",
        "-Dserver.port=$applicationPort",
        "-Dspring.profiles.active=$springActiveProfiles",
        "-Didm.realm=develop",
        proxyConfig,
        "-jar", tasks.jar.destinationDir.toString() + "/showcase-rest-SNAPSHOT.jar"

但显然这行不通。

试试这个 :

def params = ["java", "-Xmx227m",
        "-Dapplication.name=showcase-rest",
        "-Dserver.port=$applicationPort",
        "-Dspring.profiles.active=$springActiveProfiles",
        "-Didm.realm=develop",
        "-Dhttp.proxyHost=10.xx.xxx.129", "-Dhttp.proxyPort=3xxx",
        "-Dhttps.proxyHost=10.xx.xxx.129", "-Dhttps.proxyPort=3xxx",
        "-Dhttp.nonProxyHosts=localhost|127.0.0.1",
        "-jar", tasks.jar.destinationDir.toString() + "/showcase-rest-SNAPSHOT.jar"]

def withProxy = true

commandLine (*(params.findAll { withProxy || !it.toLowerCase().contains('proxy') }))
