intellij.systemProperties does not work

[huoguangjin]

According to README, I try to set system properties in this way (plugin version 0.2.1)

// other config...

def DEBUG_MODE = true

intellij {
    version 'IC-2016.2'
    pluginName 'MyPlugin'

    systemProperties = [
            "hello": "world"
    ]

    systemProperty "debug.mode", DEBUG_MODE
}

but I could not get the system properties

System.out.println("hello=" + System.getProperty("hello"));
System.out.println("debug.mode=" + Boolean.getBoolean("debug.mode"));

result:

hello=null
debug.mode=false

is there something wrong?

// other config...

def DEBUG_MODE = true

intellij {
    version 'IC-2016.2'
    pluginName 'MyPlugin'

    systemProperties = [
            "hello": "world"
    ]

    systemProperty "debug.mode", DEBUG_MODE
}

// add following lines
runIdea.doFirst {
    runIdea.systemProperties(runIdea.systemProperties)
    // or runIdea.systemProperties += [:]
}

🎉🎉 now it work!~

I check my idea.log file
there are some logs with keyword #com.intellij.idea.Main show the JVM Args options

I can get following properties from System.getProperties() correctly, but could not get the properties from intellij.systemProperties

apple.laf.useScreenMenuBar
idea.classpath.index.enabled
idea.config.path
idea.is.internal
idea.platform.prefix
idea.plugins.path
idea.required.plugins.id
idea.smooth.progress
idea.system.path

clone the repo(plugin version 0.2.1) and found:

// IntelliJPlugin.groovy
project.tasks.create(RUN_IDEA_TASK_NAME, RunIdeaTask).with {
    group = GROUP_NAME
    description = "Runs Intellij IDEA with installed plugin."
    conventionMapping.map("ideaDirectory", { Utils.ideaSdkDirectory(extension) })
    conventionMapping.map("systemProperties", { extension.systemProperties })

    // ...
}

// RunIdeaTask.groovy
def configureSystemProperties() {
    systemProperties(Utils.getIdeaSystemProperties(getConfigDirectory(), getSystemDirectory(), getPluginsDirectory(), getRequiredPluginIds()))
    def operatingSystem = OperatingSystem.current()
    if (operatingSystem.isMacOsX()) {
        systemProperty("idea.smooth.progress", false)
        systemProperty("apple.laf.useScreenMenuBar", true)
    } else if (operatingSystem.isUnix() && !getSystemProperties().containsKey("sun.awt.disablegrab")) {
        systemProperty("sun.awt.disablegrab", true)
    }
    systemProperty("idea.classpath.index.enabled", false)
    systemProperty("idea.is.internal", true)

    if (!getSystemProperties().containsKey('idea.platform.prefix')) {
        def matcher = Utils.VERSION_PATTERN.matcher(Utils.ideaBuildNumber(getIdeaDirectory()))
        if (matcher.find()) {
            def prefix = PREFIXES.get(matcher.group(1))
            if (prefix) {
                systemProperty('idea.platform.prefix', prefix)
            }
        }
    }
}

learn from Can gradle extensions handle lazy evaluation of a property? - Stack Overflow
It seems that conventionMapping.map("systemProperties", { extension.systemProperties }) will be covered by systemProperties(Utils.getIdeaSystemProperties(getConfigDirectory(), getSystemDirectory(), getPluginsDirectory(), getRequiredPluginIds()))

so the plugin setting intellij.systemProperties does not work...

add following lines in build.gradle, the problem get solved now 😃

runIdea.doFirst {
    runIdea.systemProperties(runIdea.systemProperties)
    // or runIdea.systemProperties += [:]
}

then I a make pull request, please check
