Installation

How to import SolversLib into your Android Studio FTC Project

1. Installing from FTCLib

build.gradle

The first thing you need to change from FTCLib is the dependency in build.gradle

build.gradle (Module: TeamCode)

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:0.3.2" // add SolversLib core

Or, if you are using pedroPathing, change to this dependency block

build.gradle (Module: TeamCode)

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:0.3.2" // core
    implementation "org.solverslib:pedroPathing:0.3.2" // pedroPathing
}

Important: Different versions of SolversLib correlate with different versions of Pedro Pathing.

SolversLib 0.3.3 is for Pedro Pathing 2.0.0 SolversLib 0.3.2 is for Pedro Pathing 1.0.9 SolversLib 0.3.1 is for Pedro Pathing 1.0.8

The latest version numbers (as well as a list of all version numbers) are available at:

• Latest core version: https://repo.dairy.foundation/#/releases/org/solverslib/core

• Latest pedroPathing version: https://repo.dairy.foundation/#/releases/org/solverslib/pedroPathing

Warning: If you choose to use the Pedro Pathing module, you still need to install Pedro Pathing 1.0.9 in order to use it.

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 section. Then follow the final step below (changing imports).

Lastly, follow the steps in the Changing Imports 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 https://github.com/FTC-23511/SolversLib-Quickstart. 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:

build.gradle

    repositories {
        mavenCentral()
    }

Next, minSdkVersion to 24 and multiDexEnabled to true:

build.common.gradle

defaultConfig {
    applicationId 'com.qualcomm.ftcrobotcontroller'
    minSdkVersion 24
    targetSdkVersion 28
    multiDexEnabled true

Next, change JavaVersion to 8 :

build.common.gradle

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

build.gradle

The first thing you need to change from FTCLib is the dependency in build.gradle

build.gradle (Module: TeamCode)

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:0.3.2" // add SolversLib core

Or, if you are using pedroPathing, change to this dependency block

build.gradle (Module: TeamCode)

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:0.3.2" // core
    implementation "org.solverslib:pedroPathing:0.3.2" // pedroPathing
}

Important: Different versions of SolversLib correlate with different versions of Pedro Pathing.

SolversLib 0.3.3 is for Pedro Pathing 2.0.0 SolversLib 0.3.2 is for Pedro Pathing 1.0.9 SolversLib 0.3.1 is for Pedro Pathing 1.0.8

The latest version numbers (as well as a list of all version numbers) are available at:

• Latest core version: https://repo.dairy.foundation/#/releases/org/solverslib/core

• Latest pedroPathing version: https://repo.dairy.foundation/#/releases/org/solverslib/pedroPathing

Warning: If you choose to use the Pedro Pathing module, you still need to install Pedro Pathing 1.0.9 in order to use it.

Please note that you should not and cannot have both FTCLib and SolversLib installed at the same time.

Repositories

Finally, follow the steps in the Repositories section.

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: https://repo.dairy.foundation/#/snapshots/org/solverslib/core

• Latest pedroPathing snapshot version: https://repo.dairy.foundation/#/snapshots/org/solverslib/pedroPathing

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.

build.gradle (Module: TeamCode)

repositories {
    maven {
        url "https://repo.dairy.foundation/releases"
    }
}

Only for Snapshot/Beta 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.

A Snapshot version (e.g., SNAPSHOT-7cdcc66) is a beta version.

build.gradle (Module: TeamCode)

repositories {
    maven {
        url "https://repo.dairy.foundation/releases"
    }
    maven {
        url "https://repo.dairy.foundation/snapshots"
    }
}

Changing Imports (Only if Migrating from FTCLIB)

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):

find . -type f -name "*.java" -exec sed -i '' 's/com.arcrobotics.ftclib/com.seattlesolvers.solverslib/g' {} +

SolversLib Imports to FTCLib Imports (MacOS/Linux):

find . -type f -name "*.java" -exec sed -i '' 's/com.seattlesolvers.solverslib/com.arcrobotics.ftclib/g' {} +

FTCLib Imports to SolversLib Imports (Windows):

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):

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
