# Google BeyondCorp AppConnections Client for Java
Java idiomatic client for [BeyondCorp AppConnections][product-docs].
[![Maven][maven-version-image]][maven-version-link]
![Stability][stability-image]
- [Product Documentation][product-docs]
- [Client Library Documentation][javadocs]
> Note: This client is a work-in-progress, and may occasionally
> make backwards-incompatible changes.
## Quickstart
If you are using Maven with [BOM][libraries-bom], add this to your pom.xml file:
```xml
com.google.cloud
libraries-bom
26.11.0
pom
import
com.google.cloud
google-cloud-beyondcorp-appconnections
```
If you are using Maven without the BOM, add this to your dependencies:
```xml
com.google.cloud
google-cloud-beyondcorp-appconnections
0.15.0
```
If you are using Gradle without BOM, add this to your dependencies:
```Groovy
implementation 'com.google.cloud:google-cloud-beyondcorp-appconnections:0.15.0'
```
If you are using SBT, add this to your dependencies:
```Scala
libraryDependencies += "com.google.cloud" % "google-cloud-beyondcorp-appconnections" % "0.15.0"
```
## Authentication
See the [Authentication][authentication] section in the base directory's README.
## Authorization
The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired BeyondCorp AppConnections APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the BeyondCorp AppConnections API calls.
## Getting Started
### Prerequisites
You will need a [Google Cloud Platform Console][developer-console] project with the BeyondCorp AppConnections [API enabled][enable-api].
You will need to [enable billing][enable-billing] to use Google BeyondCorp AppConnections.
[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
[installing the Google Cloud Command Line Interface][cloud-cli] and running the following commands in command line:
`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
### Installation and setup
You'll need to obtain the `google-cloud-beyondcorp-appconnections` library. See the [Quickstart](#quickstart) section
to add `google-cloud-beyondcorp-appconnections` as a dependency in your code.
## About BeyondCorp AppConnections
[BeyondCorp AppConnections][product-docs] is Google's implementation of the zero trust model. It builds upon a decade of experience at Google, combined with ideas and best practices from the community. By shifting access controls from the network perimeter to individual users, BeyondCorp enables secure work from virtually any location without the need for a traditional VPN.
See the [BeyondCorp AppConnections client library docs][javadocs] to learn how to
use this BeyondCorp AppConnections Client Library.
## Troubleshooting
To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
## Transport
BeyondCorp AppConnections uses gRPC for the transport layer.
## Supported Java Versions
Java 8 or above is required for using this client.
Google's Java client libraries,
[Google Cloud Client Libraries][cloudlibs]
and
[Google Cloud API Libraries][apilibs],
follow the
[Oracle Java SE support roadmap][oracle]
(see the Oracle Java SE Product Releases section).
### For new development
In general, new feature development occurs with support for the lowest Java
LTS version covered by Oracle's Premier Support (which typically lasts 5 years
from initial General Availability). If the minimum required JVM for a given
library is changed, it is accompanied by a [semver][semver] major release.
Java 11 and (in September 2021) Java 17 are the best choices for new
development.
### Keeping production systems current
Google tests its client libraries with all current LTS versions covered by
Oracle's Extended Support (which typically lasts 8 years from initial
General Availability).
#### Legacy support
Google's client libraries support legacy versions of Java runtimes with long
term stable libraries that don't receive feature updates on a best efforts basis
as it may not be possible to backport all patches.
Google provides updates on a best efforts basis to apps that continue to use
Java 7, though apps might need to upgrade to current versions of the library
that supports their JVM.
#### Where to find specific information
The latest versions and the supported Java versions are identified on
the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
and on [google-cloud-java][g-c-j].
## Versioning
This library follows [Semantic Versioning](http://semver.org/).
