# Installation ## 1. Installing from FTCLib ## build.gradle The first thing you need to change from FTCLib is the dependency in `build.gradle` {% code title="build.gradle (Module: TeamCode)" %} ```groovy dependencies { // implementation "org.ftclib.ftclib:core:2.1.1" remove FTCLib core // FTCLib's vision is no longer supported in SolversLib implementation "org.solverslib:core:0.2.3" // add SolversLib core ``` {% endcode %} Or, if you are using pedroPathing, change to this dependency block {% code title="build.gradle (Module: TeamCode)" %} ```groovy dependencies { // implementation "org.ftclib.ftclib:core:2.1.1" remove FTCLib core // FTCLib's vision is no longer supported in SolversLib implementation "org.solverslib:core:0.2.3" // core implementation "org.solverslib:pedroPathing:0.2.3" // pedroPathing } ``` {% endcode %} The latest version numbers (as well as a list of all version numbers) are available at: * Latest `core` version: * Latest `pedroPathing` version: {% hint style="warning" %} **Warning:** If you choose to use the Pedro Pathing module, you still need to [install Pedro Pathing](https://pedropathing.com/) in order to use it. {% endhint %} Please note that you should not and cannot have both FTCLib and SolversLib installed at the same time. **Repositories:** Then, follow the steps in the [Repositories](#repositories) section. Then follow the final step below (changing imports). #### Changing Imports: Lastly, follow the steps in the [Changing Imports](#changing-imports-1) section and then Gradle Sync! ## 2. Installing from SolversLib Quickstart An alternative option is to simply use the SolversLib Quickstart. Similar to the FTCLib Quickstart, SolversLib has a Quickstart with this library fully set up. You can view it at . You can either fork or clone this repository as needed to use it. In addition, the Quickstart also has the Pedro Pathing library installed and added along with the SolversLib pedroPathing dependency, meaning that it is hassle-free. If you don't want the Pedro Pathing part, you can simply delete the relevant files. ## 3. Installing from Scratch ## build.common.gradle First, you need to add the `mavenCentral` library repository to your `build.gradle` file at the project root: {% code title="build.gradle" %} ```groovy repositories { mavenCentral() } ``` {% endcode %} Next, `minSdkVersion` to `24` and `multiDexEnabled` to `true`: {% code title="build.common.gradle" %} ```groovy defaultConfig { applicationId 'com.qualcomm.ftcrobotcontroller' minSdkVersion 24 targetSdkVersion 28 multiDexEnabled true ``` {% endcode %} Next, change `JavaVersion` to `8` : {% code title="build.common.gradle" %} ```groovy compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } ``` {% endcode %} ## build.gradle The first thing you need to change from FTCLib is the dependency in `build.gradle` {% code title="build.gradle (Module: TeamCode)" %} ```groovy dependencies { // implementation "org.ftclib.ftclib:core:2.1.1" remove FTCLib core // FTCLib's vision is no longer supported in SolversLib implementation "org.solverslib:core:0.2.3" // add SolversLib core ``` {% endcode %} Or, if you are using pedroPathing, change to this dependency block {% code title="build.gradle (Module: TeamCode)" %} ```groovy dependencies { // implementation "org.ftclib.ftclib:core:2.1.1" remove FTCLib core // FTCLib's vision is no longer supported in SolversLib implementation "org.solverslib:core:0.2.3" // core implementation "org.solverslib:pedroPathing:0.2.3" // pedroPathing } ``` {% endcode %} The latest version numbers (as well as a list of all version numbers) are available at: * Latest `core` version: * Latest `pedroPathing` version: {% hint style="warning" %} **Warning:** If you choose to use the Pedro Pathing module, you still need to [install Pedro Pathing](https://pedropathing.com/) in order to use it. {% endhint %} ## Snapshot Versions SolversLib is graciously hosted on the Dairy Foundation (thanks to Oscar!), and has release versions and snapshots versions. * Release versions: * Are official, verified versions of SolversLibs * Less likelier to have problems/bugs * Are in the form: `implementation "org.solverslib:core:x.y.z"` (where x, y, and z are version numbers). * Snapshots versions: * Are unofficial, and effectively beta versions with newere features and additions * More likelier to have problems/bugs * Are in the form: `implementation "org.solverslib:pedroPathing:SNAPSHOT-abc1234"` (7 random letters & numbers). For most people, it is HIGHLY recommended to use the releases versions. Should you still want to use the snapshots versions instead of releases, you can use the dependencies instead: * Latest `core` snapshot version: * Latest `pedroPathing` snapshot version: **Repositories:** Look at the section below. Make sure to follow the snapshot versions part. ## Repositories In your repositories block, add the following code. You may have other content here, especially if you have the Pedro Pathing library installed. If you do not have a repositories block, you can add it above your dependencies block. {% code title="build.gradle (Module: TeamCode)" %} ```groovy repositories { maven { url "https://repo.dairy.foundation/releases" } } ``` {% endcode %} #### Only for Snapshot Versions You also need to add the maven for snapshots in your repositories block in addition to the releases one. Again, if you do not have a repositories block, you can add it above your dependencies block. {% code title="build.gradle (Module: TeamCode)" %} ```groovy repositories { maven { url "https://repo.dairy.foundation/releases" } maven { url "https://repo.dairy.foundation/snapshots" } } ``` {% endcode %} ## Changing Imports Because the package names will be different, you can either manually replace all instances of `com.arcrobotics.ftclib` with `com.seattlesolvers.solverslib` , or use a command in a terminal to replace them all at once for you. Please make sure you either open a terminal into your Android Studio project or use the built-in Android Studio terminal to run the commands below. **FTCLib Imports to SolversLib Imports (MacOS/Linux):** ```bash find . -type f -name "*.java" -exec sed -i '' 's/com.arcrobotics.ftclib/com.seattlesolvers.solverslib/g' {} + ``` **SolversLib Imports to FTCLib Imports (MacOS/Linux):** ```bash find . -type f -name "*.java" -exec sed -i '' 's/com.seattlesolvers.solverslib/com.arcrobotics.ftclib/g' {} + ``` **FTCLib Imports to SolversLib Imports (Windows):** ```powershell Get-ChildItem -Recurse -Filter *.java | ForEach-Object { (Get-Content $.FullName) -replace 'com.arcrobotics.ftclib', 'com.seattlesolvers.solverslib' | Set-Content $.FullName } ``` **SolversLib Imports to FTCLib Imports (Windows):** ```powershell Get-ChildItem -Recurse -Filter *.java | ForEach-Object { (Get-Content $.FullName) -replace 'com.seattlesolvers.solverslib', 'com.arcrobotics.ftclib' | Set-Content $.FullName } ``` ### Sync Gradle and Finished! ![Click that button and if successful, you can now use SolversLib](https://content.gitbook.com/content/kOVn6uTPgm8WvHRygMWb/blobs/IgUI5SOeZ1tTpyNkf6Sx/gradle-sync.png)
