I have installed Gradle by adding the path to it into the system variables. I am quite new to Java and this is the first time that I am trying to install an external library for it. On the Mockito web-page, they say that one can:
Declare a dependency on “mockito-core” library using your favorite
build system. With Gradle one can do:
repositories { jcenter() }
dependencies { testCompile "org.mockito:mockito-core:1.+" }
So I have no idea what it means. I changed the directory in cmd to the Gradle folder and tried to execute these commands, but that is not how one is supposed to do it. Can you give me a hand here?
You have to create a build.gradle file where you can insert the dependency. I recommend using an ide like eclipse or IntelliJ which can generate a gradle project for you so you don't have to do this manually. Just install the corresponding Gradle Plugin. This also makes sure you have a correct project structure.

Every time I run this command: gradle build it produces a my-program-1.0.0-SNAPSHOT.jar. Where do I control this? In the gradle.properties I have only the version nothing else. Even if I run gradle -Dversion=1.0.0 build it still creates a jar with SNAPSHOT in the name. How do I create a jar like this: my-program-1.0.0.jar?
I'm using spring boot.
Basically we have to change the project version in the gradle, To do so we have to use project api in gradle. you can refer https://docs.gradle.org/current/dsl/org.gradle.api.Project.html
One Solution I can suggest is:
Add version '1.0' in your build.gradle
I am coming from a C# background. I am used to NuGet and Visual Studio project references so the Java ecosystem has confused me quite a bit.
I have a gradle library project. I want to import org.apache.commons.codec.binary.Base64;
However I keep getting cannot resolve errors.
I am using VSCode as my IDE and I would like to include the codec dependancy. How would I achieve this in VSCode/gradle.
I have downloaded the commons-codec-1.14.jar file, but don't know where to put it in the project.
Gradle is a tool that, among other things, manages your dependencies. This means that, you do not need to manually download and add dependencies to your project. Gradle solves this for you.
See the official documenation on how to handle dependencies with Gradle.
You probably have a build.gradle file, in which you need to include your dependency. It would look something like:
dependencies {
implementation 'commons-codec:commons-codec:1.14'
}
This lets Gradle know that you have a dependency to version 1.14 of commons-codec which your codes need to build and run.
This will automatically be downloaded from a remote repository, which you also can specify in your build.gradle file:
repositories {
mavenCentral()
}
This tells gradle to download the dependencies from Maven Central, which probably is the most typical Maven/Gradle repository and most likely hosts most dependencies you would need.
I'm still fairly new to development and don't know how to solve my problem.
I have a project that needs other code for it to work.
I understand that by adding a path n the import section of my java gives access to a library.
I also understand that by adding a compile dependency to my build.gradle file, tells it where that library is.
My question is two part:
What do I do when it fails to resolve dependency?
I have downloaded the source code off of git hub.
I want to be able to add the source to my project.
Now, I don't want to add it directly to my package, but the way gradle does it. Just by pointing to it.
So my real question, how do I get a library into my code without adding the entire source code into the package?
What would I have to do in my import section of my java file?
P.S.
Thanks in advance.
Since I'm still learning the concepts, my question might not be structured in the best manner.
You could create a jarfile from the those sources:
jar cf program.jar -C path/to/classes .
source: https://stackoverflow.com/a/18146453/7625131
further information: https://docs.oracle.com/javase/tutorial/deployment/jar/build.html
After that you just have to reference it using gradle:
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
compile name: 'gson-2.2.4'
}

As Mett highlighted. Create a jar of the project that you cloned from github. Add it in the buildpath of your desired project . If you are using a build automation tool like maven or gradle , then install the jar in your local repository. Then use it as a dependency in your project.
In gradle, when running my script, I have a bunch of sub-projects that are dependent on others. We need to pull them in as external jars (not compile project for various reasons). So I need them installed locally. I want this to be a function defined in the parent gradle.
When I try to call install ":projName" inside a function, I get the error:
Could not find method install() for arguments [:projName] on root project 'test' of type org.gradle.api.Project
How would I do this?
ext.installLocal = {moduleName ->
//...elided... doing some checking, conditionals, etc
//Try to install locally
install ":${moduleName}"
}
You need to add build.finalizedBy(publishToMavenLocal) command to all your subprojects build.gradle file that need to be pushed in your maven local. If your need to push all your subprojects to maven local, you can call this command in subprojects{ } closure in main build.gradle file. But remember if subprojects are dependent on each other their build order is critical.
I want to use Mockito in my Eclipse, and you can only install it through build programs such as maven or Gradle, I chose to use Gradle. I am a beginner in using Gradle, but I just need to install Mockito and be able to use it as a dependency.
You don't actually "install" Mockito. You just add it to your dependency management system. Since you're using Gradle, all you have to do is add it to your build.gradle file. I'm assuming you've started with a blank Gradle project or something like that, which included a default build.gradle file.
Somewhere in that file you'll declare all your project dependencies:
dependencies {
// other dependencies will be here, just add the following line:
testCompile("org.mockito:mockito-core:1.10.19")
}
You can find out Mockito's artifact/group ids and available versions here: http://mvnrepository.com/search?q=mockito
