Execution failed for task ':createScmAdapter'.

[tdelphi]

I was trying to see how gradle-release plugin works, but got bored after 4 errors..

How to reproduce:

1. create empty directory and cd to it
2. run gradle init
3. uncomment all content to make build.gradle look like that:
   `/*

• This build file was auto generated by running the Gradle 'init' task
• by 'tdelphi' at '6/1/16 11:47 PM' with Gradle 2.2.1
  *
• This generated file contains a commented-out sample Java project to get you started.
• For more details take a look at the Java Quickstart chapter in the Gradle
• user guide available at http://gradle.org/docs/2.2.1/userguide/tutorial_java_projects.html
  */

plugins {
id 'net.researchgate.release' version '2.4.0'
}

// Apply the java plugin to add support for Java
apply plugin: 'java'

task wrapper(type: Wrapper) {
gradleVersion = '2.13'
}

// In this section you declare where to find the dependencies of your project
repositories {
// Use 'jcenter' for resolving your dependencies.
// You can declare any Maven/Ivy/file repository here.
jcenter()
}

// In this section you declare the dependencies for your production and test code
dependencies {
// The production code uses the SLF4J logging API at compile time
compile 'org.slf4j:slf4j-api:1.7.7'

// Declare the dependency for your favourite test framework you want to use in your tests.
// TestNG is also supported by the Gradle Test task. Just change the
// testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
// 'test.useTestNG()' to your build script.
testCompile "junit:junit:4.11"

}

4. Add "plugins" section
5. run gradlew release
6. see error:

Any news about this issue?

Hi, like the output is telling you

You have unversioned files:

You have to commit and push all your stuff in order to create a release. If you want to create one with unversioned files, tell it to the plugin by configuration.

Look at the following example where i reproduced your setup.

I also faced same issue, followed below workaround answered on StackOverflow.

git update-index --chmod=+x gradlew
git commit

execute above commends in your application.
