Need help with mainTemplate.gradle (Unity 2019.3.2f1)

When I create an mainTemplate.gradle file it will create this

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

apply plugin: 'com.android.library'
**APPLY_PLUGINS**

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
**DEPS**}

android {
    compileSdkVersion **APIVERSION**
    buildToolsVersion '**BUILDTOOLS**'

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        minSdkVersion **MINSDKVERSION**
        targetSdkVersion **TARGETSDKVERSION**
        ndk {
            abiFilters **ABIFILTERS**
        }
        versionCode **VERSIONCODE**
        versionName '**VERSIONNAME**'
        consumerProguardFiles 'proguard-unity.txt'**USER_PROGUARD**
    }

    lintOptions {
        abortOnError false
    }

    aaptOptions {
        ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:.*:!CVS:!thumbs.db:!picasa.ini:!*~"
    }**PACKAGING_OPTIONS**
}**REPOSITORIES****SOURCE_BUILD_SETUP**
**EXTERNAL_SOURCES**

and I have to do this two steps

  1. What dose it mean with “Maven URL”.
  2. Where can I find the build.gradle file.
  3. What should I do now??
