How to use Oracle JDBC driver in Gradle project

I'm new with Gradle projects and I have one question. I've searched in Internet but I couldn't find what I need or maybe I couldn't know how to search it. First I'm going to tell you my case. I have a Gradle project and I would like to execute several automated tests, in the future with jenkins, but now I want to try on Eclipse. I have the oracle jdbc driver in /lib directory, and this is my build.gradle

    apply plugin: 'java'

// In this section you declare where to find the dependencies of your project
repositories {
    jcenter()
    //mavenCentral()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    compile 'org.slf4j:slf4j-api:1.7.21'
    compile 'org.seleniumhq.selenium:selenium-java:2.+'
    compile 'org.testng:testng:6.+'
    //compile 'com.oracle:ojdbc14:10.2.0.4.0'
    //testCompile 'net.sourceforge.jexcelapi:jxl:2.6.12'
    testCompile 'info.cukes:cucumber-core:1.+'
    testCompile 'info.cukes:cucumber-java:1.+'
    testCompile 'info.cukes:cucumber-junit:1.+'
    testCompile 'junit:junit:4.12'
}

repositories {
  flatDir(dir: 'libs')//, name: 'Local libs'
}

dependencies {
  compile name: 'ojdbc7'
}

I'd like to use this jdbc driver in one class but I don't know how to use it. When I tried with Maven I used this way "import oracle.jdbc.driver.OracleDriver;" but I guess this is not valid for Gradle project. Can you help me, please? Thanks in advance

You can simply add a jar as dependency, like so:

compile files('libs/ojdbc7.jar')

And there is no need to add a flatDir repository in that case. Read about it in the official user guide

You can try reusing your local Maven repository for Gradle:

Download ojdbc7.jar from Oracle site

Install the jar into your local Maven repository:

mvn install:install-file -Dfile=ojdbc7.jar -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.1 -Dpackaging=jar

Check that you have the jar installed into your ~/.m2/ local Maven repository

Enable your local Maven repository in your build.gradle file:

repositories {  
    mavenCentral()  
    mavenLocal()  
}  

dependencies {  
    compile ("com.oracle:ojdbc7:12.1.0.1")  
}

Now you should have the jar enabled for compilation in your project

In addition to correct answer, I want to share my experience how I solve a problem with ojdbs dependence (used gradle and Intellij Idea).

Go to the oracle site and download jdbs file(s). I chose to download the full archive - ojdbc8-full.tar.gz
Unpack the archive in someone directory (for example c:\folder\OJDBC8-Full)
In Intellij Idea go to the Project Structure/Libraries, press "+" symbol and specify a path to the folder there archive unpacked (OJDBC8-Full). Specify name:

In build.gradle add:

dependencies {

...

compile files('libs/OJDBC8-Full') //OJDBC8-Full - it is name what you specify for librare

...

}

Since SSO-based authentications are not available in gradle:

Currently you have 3 alternatives:

download manually and copy the file (see above)
use a proxy to authenticate (and register an account for oracle maven repo)
if you have an internal repository: you can use your repo to proxy/cache oracle's one (e.g.: Nexus Oracle settings: https://support.sonatype.com/hc/en-us/articles/213465728-How-to-configure-a-proxy-repository-to-maven-oracle-com)

(+1 use maven)

other than mavenCentral use local maven repository as well for our dependencies. The reason for using the local maven repository is because the jdbc driver from Oracle is not publicly accessible. We will have to download the driver from Oracle and install it in our local maven repo.

repositories {
    mavenLocal()
}

dependencies {
    compile ("com.oracle:ojdbc6:12.2.0.1")
}

mvn install:install-file -Dfile="\ojdbc6.jar" -DgroupId="com.oracle" -DartifactId="ojdbc6" -Dversion="12.2.0.1" -Dpackaging="jar" -DgeneratePom="true"
