What is the difference between using `gradlew` and `gradle` or are they the same?

Difference between using gradlew and gradle

After committing my project&#39;s `gradlew` file from my Windows machine to the remote repo using Git, invoking `gradlew` on my Linux server failed with this message:

&gt; /usr/bin/env: bash: No such file or directory

What happened?


Error with gradlew: /usr/bin/env: bash: No such file or directory

What exactly is the difference between Android Studio&#39;s Gradle options:

`Android Studio-&gt;Preferences-&gt;Gradle`

`Use default gradle wrapper (recommended)` and `Use customizable gradle wrapper`?

Background:

I am working on an Android project in Android Studio and using a Gradle wrapper.

However, when I use the Android Studio settings &quot;Use customizable gradlew wrapper&quot; every time my team members sync the Android Studio project using the gui command:

![enter image description here][1]


  [1]: http://i.stack.imgur.com/dzkmx.png

they find the `gradle/wrapper/gradle-wrapper.properties` date being updated (and resulting in a extra diffs on the git repo).

Switching to &quot;Use default gradle wrapper&quot; seems to solve this issue.

Android Studio: &quot;Use default gradle wrapper&quot; vs. &quot;Use customizable gradle wrapper&quot;

I cleaned the whole project by deleting local directories like `~/.gradle`, `~/.m2` `~./android` and `~/workspace/project/.gradle` and chosing `File -&gt; Invalidate Caches / Restart...` in Android Studio.
Now execution of the command `./gradlew` leads to the following output:

    usr$ ./gradlew tasks
    Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

Needless to say, I deleted too much, the question is how can it be repaired again? Do you have any ideas how to fix this? 

Could not find or load main class org.gradle.wrapper.GradleWrapperMain

I am trying to understand how the Gradle Wrapper works. In many source repos, I see the following structure:

    projectRoot/
        src/
        build.gradle
        gradle.properties
        settings.gradle
        gradlew
        gradlew.bat
        gradle/
            wrapper/
                gradle-wrapper.jar
                gradle-wrapper.properties
		
My questions:

 1. How/when does one generate `gradlew`/`gradlew.bat`? Are you supposed to generate them only one time when the project is first created, do you generate them every time you commit/push changes? And how are they generated?
 2. Same question above, but for the `gradle/wrapper/*` files (`gradle-wrapper.jar` and `gradle-wrapper.properties`)?
 3. Some times I see other `*.gradle` files inside the project&#39;s `gradle` directory. What are these additional Gradle files and what do they represent/do? Custom plugins?
 4. What is the difference in properties that go into `settings.gradle` vs what should be defined inside `gradle.properties`?

How/when to generate Gradle wrapper files?

The Problem is that i am able to run my app when i change to `debug` mode but it fails when i switch to `release` mode.

It seems i am able to get my release build working if i remove `minifyEnabled true` from it. Why is that, is there another way to solve it

I&#39;ve been trying to get ActionBarSherlock to work and having some issue.  One issue I&#39;ve come across is the following message when trying to build it:

Can you help?

Android Studio: Plugin with id &#39;android-library&#39; not found

After updating Android Studio to version 2.2 (on Windows 10) and somehow next morning I received such error when gradle built on any project: 

&gt;  Write access is allowed from event dispatch thread only

Despite that gradlew -build command worked and completed successfully. 
I tried typical Android dev&#39;s of WTF repairing set: clean build, invalidate caches, removing build folders, removing .gradle folder, tried different gradle settings, even reinstalling Android Studio and nothing helped.

I&#39;ve created this question only to share my experience with community, because I wasted two hours on it. 

Gradle error: Write access is allowed from event dispatch thread only in Android Studio

I want to use Gradle **1.10** instead of **1.9.** I cannot seem to find where to change this.

If I put this:

    task wrapper(type: Wrapper) {
        gradleVersion = &#39;1.10&#39;
    }

in my `build.gradle` and rebuild, it is built with Gradle **1.9** again (so nothing actually happens).

These seem to be all the settings: (and IntelliJ&#39;s [help section about Gradle](http://www.jetbrains.com/idea/webhelp/gradle-2.html) doesn&#39;t help at all :( )

How to change the version of the &#39;default gradle wrapper&#39; in IntelliJ IDEA?

I&#39;m trying to build a gradle project with gradle-wrapper (`gradlew`).

When I build with `./gradlew build`, it outputs text

&gt; Downloading http://services.gradle.org/distributions/gradle-1.11-bin.zip

And I already got *gradle-1.11-bin.zip* downloaded separately and I don&#39;t want to be downloading it again when I build.

So, where shall I put gradle-1.11-bin.zip in my project or system so that I don&#39;t have to download again?

*gradle/wrapper/gradle-wrapper.properties* is as following. 

    distributionBase=GRADLE_USER_HOME
    distributionPath=wrapper/dists
    zipStoreBase=GRADLE_USER_HOME
    zipStorePath=wrapper/dists
    distributionUrl=http\://services.gradle.org/distributions/gradle-1.11-bin.zip

And I&#39;ve tried copying *gradle-1.11-bin.zip* into *gradle/wrapper/dists* which didn&#39;t solve the problem.

What the question says really - can you issue any commands directly to gradlew via the command line to build, package and deploy to a device?

So from what I can see, it&#39;s failing during search for `tools.jar` - which I have under `/usr/lib/jvm/default-java/lib`, since the configured path is to JDK.

My `gradle.build` - just in case:

```
plugins {
    id &#39;org.jetbrains.kotlin.jvm&#39; version &#39;1.3.11&#39;
}

ext {
    ktorVersion = &quot;1.1.2&quot;
}

group &#39;com.example&#39;
version &#39;1.0-SNAPSHOT&#39;

repositories {
    jcenter()
    mavenCentral()
}

dependencies {

compileKotlin {
    kotlinOptions.jvmTarget = &quot;1.8&quot;
}
compileTestKotlin {
    kotlinOptions.jvmTarget = &quot;1.8&quot;
}

```
I&#39;m truly at a loss, would appreciate some help. 

If any more information is needed let me know and I&#39;ll do my best to provide it.

Kotlin could not find the required JDK tools in the Java installation

I am attempting to run gradlew from my command line, but am constantly facing the following error.

    Brendas-MacBook-Pro:appx_android brendalogy$ ./gradlew compileDebug --stacktrace
    -bash: ./gradlew: Permission denied

I am already running this command from my project directory. Need to run this command as I am facing the same (nondescriptive) error on Android Studio 0.2.x as encountered here: [Android studio and gradle build error][1]

Am I doing something wrong and how do I get around this?

gradlew: Permission Denied

I&#39;ve been trying to compile and test a large project to use Gradle. The test run fine until they die unexpectedly. I dug around and resources said that this is due to a memory issue. If I reduce the number of tests in the suite, it runs fine.

I increased the memory by 4x increased the debugging level but I still don&#39;t follow what causes this. Here&#39;s the horribly cryptic stacktrace. The last line (scroll right) shows the memory settings that I&#39;ve defined.

Why are my Gradle builds dying with exit-code 137?

What is the difference between the following statements when issued from a Android Studio Project&#39;s terminal :

&gt; Android_Studio_Project_Path: ./gradlew clean
&gt;
&gt; Android_Studio_Project_Path: ./gradlew clean assembleDebug
&gt;
&gt; Android_Studio_Project_Path: ./gradlew clean :assembleDebug 
&gt;
&gt; and normal Android Studio --&gt; Build --&gt; Clean.

What would be the difference in the internal process.
