This should work:

    println GroovySystem.version

So long as you are on Groovy 1.6.6+

Before that, it was:

    println org.codehaus.groovy.runtime.InvokerHelper.version

But that&#39;s been removed from later versions of Groovy

To improve slightly on [tim_yates&#39; answer](https://stackoverflow.com/a/18876543/1580487), here&#39;s the universal code to get Groovy version:

``` groovy
public String getGroovyVersion() {
        try {
                return org.codehaus.groovy.runtime.InvokerHelper.version
        }
        catch (Throwable ignore) { }
        return GroovySystem.version
}

println getGroovyVersion()
```


I am migrating my application to iOS 7. For handing the status bar issue I have added this code


    if([[[UIDevice currentDevice] systemVersion] floatValue] &gt;= 7.0f)
    {
        CGRect frame = self.navigationController.view.frame;
        if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
        {
            frame.origin.y = 20;
        }
        else
        {
            frame.origin.x = 20;
        }
        [self.navigationController.view setFrame:frame];
    }
    

This is working fine in normal case. If I am changing orientation (app supports only landscape orientation) or presenting any view controller and dismissing model view controller my view controller alignment changed. The status bar again overlaps my view controller. This piece of code is not working at all. Please guide me to fix this status bar issue.  

Case 2: This is how I am presenting my view controller
        
    ZBarReaderViewController *reader = [ZBarReaderViewController new];
    reader.readerDelegate = self;
        
    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        reader.supportedOrientationsMask = ZBarOrientationMaskLandscape;
    else
        reader.supportedOrientationsMask = ZBarOrientationMaskPortrait;
        
        [self presentModalViewController:reader animated:YES];

Status bar and navigation bar issue in IOS7

I created an array of objects like so:

``` js
[
    {
        &quot;lat&quot;: 12.123,
        &quot;lng&quot;: 13.213,
        &quot;city&quot;: &quot;New York&quot;
    },
    {
        &quot;lat&quot;: 3.123,
        &quot;lng&quot;: 2.213,
        &quot;city&quot;: &quot;New York&quot;
    },
    {
        &quot;lat&quot;: 1.513,
        &quot;lng&quot;: 1.113,
        &quot;city&quot;: &quot;London&quot;
    }
]
```

I&#39;m trying to create a new array that filters the `places` to only contains objects that don&#39;t have the same `city` property (lat/lng duplicates are ok). Is there a built in JS or Jquery function to achieve this?

I need to be able to find out the version of Groovy runtime via a groovy script.
How do I do it? The examples I found on the net show a way, but apparently it has been deprecated and removed in the latest version.

How can exceptions be tested in a nice way (e.g. data tables) with Spock?

Example: Having a method `validateUser` that can throw exceptions with different messages or no exception if the user is valid.

The specification class itself:

    class User { String userName }
    
    class SomeSpec extends spock.lang.Specification {

        ...tests go here...

        private validateUser(User user) {
            if (!user) throw new Exception (&#39;no user&#39;)
            if (!user.userName) throw new Exception (&#39;no userName&#39;)
        }
    }


**Variant 1**

This one is working but the real intention is cluttered by all the *when* / *then* labels and the repeated calls of `validateUser(user)`.

        def &#39;validate user - the long way - working but not nice&#39;() {
            when:
            def user = new User(userName: &#39;tester&#39;)
            validateUser(user)
    
            then:
            noExceptionThrown()
    
            when:
            user = new User(userName: null)
            validateUser(user)
    
            then:
            def ex = thrown(Exception)
            ex.message == &#39;no userName&#39;
    
            when:
            user = null
            validateUser(user)
    
            then:
            ex = thrown(Exception)
            ex.message == &#39;no user&#39;
        }


**Variant 2**

This one is not working because of this error raised by Spock at compile time:

*Exception conditions are only allowed in &#39;then&#39; blocks*

        def &#39;validate user - data table 1 - not working&#39;() {
            when:
            validateUser(user)
    
            then:
            check()
    
            where:
            user                         || check
            new User(userName: &#39;tester&#39;) || { noExceptionThrown() }
            new User(userName: null)     || { Exception ex = thrown(); ex.message == &#39;no userName&#39; }
            null                         || { Exception ex = thrown(); ex.message == &#39;no user&#39; }
        }


**Variant 3**

This one is not working because of this error raised by Spock at compile time:

*Exception conditions are only allowed as top-level statements*

        def &#39;validate user - data table 2 - not working&#39;() {
            when:
            validateUser(user)
    
            then:
            if (expectedException) {
                def ex = thrown(expectedException)
                ex.message == expectedMessage
            } else {
                noExceptionThrown()
            }
    
            where:
            user                         || expectedException | expectedMessage
            new User(userName: &#39;tester&#39;) || null              | null
            new User(userName: null)     || Exception         | &#39;no userName&#39;
            null                         || Exception         | &#39;no user&#39;
        }

Unfortunately `stripIndent` on a multiline string does not work.
Side note: My IDE code style preferences allow only space indentation (tabs will be replaced by spaces). But I think this should have no matter.

    def s = &quot;&quot;&quot; This 
                is
                multiline
    &quot;&quot;&quot;
    println s.stripIndent()
does not print 

    This
    is
    multiline

 as expected.

The output is with indentation.

    This 
                   is
                   multiline

What is going wrong here?

I use Groovy 2.0.7 with Eclipse Indigo SR2.

The problem seems to disappear with the use of the *backslash* `\` (String continuation character) in first line. But I don&#39;t understand why this is a must.

Strip indent in Groovy multiline strings

I have a Gradle build script into which I am trying to include [Eric Wendelin&#39;s CSS plugin][1].

It&#39;s easy enough to implement, and because I only want minification (rather than combining and gzipping), I&#39;ve got the pertinent parts of the build script looking like this:

    minifyCss {
        source = &quot;src/main/webapp/css/brandA/styles.css&quot;
        dest = &quot;${buildDir}/brandA/styles.css&quot;
        yuicompressor {
            lineBreakPos = -1
        }
    }
    
    war {
        baseName = &#39;ex-ren&#39;
    }

    war.doFirst {
        tasks.myTask.minifyCss.execute()
    }

This is perfect - when I run the gradle war task, it calls the minifyCss task, takes the source css file, and creates a minified version in the buildDir

However, I have a handful of css files which need minify-ing, but not combining into one file (hence I&#39;m not using the combineCss task)

What I&#39;d like to be able to do is make the source and dest properties (assuming that&#39;s the correct terminology?) of the minifyCss task reference variables of some sort - either variables passed into the task in the signature, or global variables, or something ...

Something like this I guess (which doesn&#39;t work):

    minifyCss(sourceFile, destFile) {
        source = sourceFile
        dest = destFile
        yuicompressor {
            lineBreakPos = -1
        }
    }
    
    war {
        baseName = &#39;ex-ren&#39;
    }

    war.doFirst {
        tasks.myTask.minifyCss.execute(&quot;src/main/webapp/css/brandA/styles.css&quot;, &quot;${buildDir}/brandA/styles.css&quot;)
        tasks.myTask.minifyCss.execute(&quot;src/main/webapp/css/brandB/styles.css&quot;, &quot;${buildDir}/brandB/styles.css&quot;)
        tasks.myTask.minifyCss.execute(&quot;src/main/webapp/css/brandC/styles.css&quot;, &quot;${buildDir}/brandC/styles.css&quot;)
    }

This doesn&#39;t work either:

    def sourceFile = null
    def destFile = null

    minifyCss {
        source = sourceFile
        dest = destFile
        yuicompressor {
            lineBreakPos = -1
        }
    }
    
    war {
        baseName = &#39;ex-ren&#39;
    }

    war.doFirst {
        sourceFile = &quot;src/main/webapp/css/brandA/styles.css&quot;
        destFile = &quot;${buildDir}/brandA/styles.css&quot;
        tasks.myTask.minifyCss.execute()
    }


For the life of me I cannot work out how to call a task and pass variables in :(

Any help very much appreciated;

How to get values from properties file using Groovy?

I require to have a property file (.properties) which would have file names as key, and their destination path as the value. I will need the key to be resolved at runtime, depending on file that needs to be moved. 

So far I am able to load the properties it seems but can&#39;t &quot;get&quot; the value from the loaded properties.

I referred to the thread : https://stackoverflow.com/questions/2055959/groovy-how-to-access-to-properties-file and following is the code snippet i have so far 

    def  props = new Properties();
	File propFile = 
              new File(&#39;D:/XX/XX_Batch/XX_BATCH_COMMON/src/main/resources/patchFiles.properties&#39;)
	props.load(propFile.newDataInputStream())
	def config = new ConfigSlurper().parse(props)
		def ant = new AntBuilder()
		def list = ant.fileScanner {
					fileset(dir:getSrcPath()) {
		            	include(name:&quot;**/*&quot;)
		            }
	    }
		for (f in list) {
		   def key = f.name
		   println(props)
		   println(config[key])
		   println(config)
		   def destn = new File(config[&#39;a&#39;])
			
		}

the properties file has the following entries for now : 

    jan-feb-mar.jsp=/XX/Test/1
    XX-1.0.0-SNAPSHOT.jar=/XX/Test/1
    a=b
    c=d
    

Correct values are returned if I look up using either props.getProperty(&#39;a&#39;)
or,
config[&#39;a&#39;]
Also tried the code: notation

But as soon as switch to using the variable &quot;key&quot;, as in config[key] it returns --&gt; [:]

I am new to groovy, can&#39;t say what am i missing here.

How to do code something like this in `groovy`?

    do {
    
      x.doIt()
    
    } while (!x.isFinished())

Because there is *no `do ... while` syntax* in groovy.

&gt; **No &#39;do ... while()&#39; syntax as yet.**
&gt;
&gt; Due to ambiguity, we&#39;ve not yet added support for do .. while to Groovy
