blocks|key|767422|text|Gradle构建脚本是用Groovy编写的。Groovy既有双引号的字符串，也有单引号的字符串。主要区别在于双引号的字符串文字支持字符串插值：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|767423|def+x+=+10

Gradle build scripts are written in Groovy. Groovy has both double-quoted and single-quoted String literals. The main difference is that double-quoted String literals support String interpolation:

<pre><code>def x = 10
println "result is $x" // prints: result is 10
</code></pre>

You can learn more about Groovy String interpolation in <a href="http://en.wikipedia.org/wiki/Groovy_%28programming_language%29#String_Interpolation">this</a> or other Groovy articles on the web.

blocks|key|769551|text|是的，你可以选择其中之一。唯一的区别是双引号字符串可以是GStrings，它可以包含如下取自the+Groovy+documentation的示例中的求值表达式|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|769552|foxtype+=+'quick'

Yes, you can use one or the other. The only difference is that double-quoted strings can be GStrings, which can contain evaluated expressions like in the following example taken from <a href="http://groovy.codehaus.org/Strings+and+GString">the Groovy documentation</a>:

<pre><code>foxtype = 'quick'
foxcolor = ['b', 'r', 'o', 'w', 'n']
println "The $foxtype ${foxcolor.join()} fox"
// =&gt; The quick brown fox
</code></pre>

According to the gradle <a href="https://guides.gradle.org/style-guide/#favor_single_quotes_for_plain_strings_in_build_script_listings" rel="noreferrer">docs</a>:
<blockquote>
Favor single quotes for plain strings in build script listings
This is
mostly to ensure consistency across guides, but single quotes are also
a little less noisy than double quotes. Only use double quotes if you
want to include an embedded expression in the string.
</blockquote>

blocks|key|2009918|text|单引号字符串是由单引号括起来的一系列字符。像这样：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2009919|def+str='a+single+quoted+string'
println+str|code-block|syntax|javascript|2009920|输出：|2009921|a+single+quoted+string|2009922|尽管双引号字符串允许我们在这里使用字符串插值，但我们有一个带有引用局部变量的占位符的字符串：|2009923|def+name+=+'Guillaume'+//+a+plain+string
def+greeting+=+"Hello+${name}"|2009924|输出：Hello+Guillaume|CODE|2009925|在您的代码中，如果您想要打印任务名称。因此，在这种情况下，您需要使用双引号：|2009926|defaultTasks+'clean',+'run'

task+clean+<<+{
++++println+'Default+Cleaning!'
}

task+run+<<+{
++++println+"Default+Running+$run.name!"

Single-quoted strings are a series of characters surrounded by single quotes.
like : 

<pre><code>def str='a single quoted string'
println str
</code></pre>

Ouput : 

<pre><code>a single quoted string
</code></pre>

Whereas Double-quoted strings allow us the String interpolation
Here, we have a string with a placeholder referencing a local variable:

<pre><code>def name = 'Guillaume' // a plain string
def greeting = "Hello ${name}"
</code></pre>

Output : <code>Hello Guillaume</code>

In your code,If you want to print the task name. So in that case, you need to use Double-quotes:

<pre><code>defaultTasks 'clean', 'run'

task clean &lt;&lt; {
 println 'Default Cleaning!'
}

task run &lt;&lt; {
 println "Default Running $run.name!"
 // here Double Quotes are required to interpolate task-name
}

task other &lt;&lt; {
 println "I'm not a default task!"
}
</code></pre>

blocks|key|2009969|text|Kotlin+DSL文件(如build.gradle.kts或settings.gradle.kts)是常规的Kotlin代码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2009970|因此，字符串文字总是用双引号括起来：|2009971|val+myFirstString+=+"4+/+2+equals+${4+/+2}"
val+mySecondString+=+"""The+property+"hide"+was+not+found"""|code-block|syntax|javascript|2009972|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Kotlin DSL files (like build.gradle.kts or settings.gradle.kts) are regular Kotlin code. 
So, string literal are always wrapped in double quotes:
<pre class="lang-kotlin prettyprint-override"><code>val myFirstString = &quot;4 / 2 equals ${4 / 2}&quot;
val mySecondString = &quot;&quot;&quot;The property &quot;hide&quot; was not found&quot;&quot;&quot;
</code></pre>

I'm new to gradle and am currently just trying to follow the tutorials and quite a few times I've seen single and double quotes intermixed. I just wanted to know if there was a difference of when one set should be used over the other. One example of this is section 6.12 of the tutorial - <a href="http://www.gradle.org/docs/current/userguide/tutorial_using_tasks.html">Default tasks</a>:

<pre><code>defaultTasks 'clean', 'run'

task clean &lt;&lt; {
 println 'Default Cleaning!'
}

task run &lt;&lt; {
 println 'Default Running!'
}

task other &lt;&lt; {
 println "I'm not a default task!"
}
</code></pre>

So, I would just like to know if I should be paying attention to these differences or if they are inter-changable and I can use either single or double quotes when printing strings in gradle.
