Running as a stand-alone server on macOS

The stand-alone server is currently used on a machine runing macOS. The server is used to build darwin targets (macOS+iOS) using the Apple tools (XCode+Apple Clang). It is also possible to use this setup when developing on macOS.

Prerequisites

Before running Extender you need to have prepackaged toolchains and sdks. Full instruction how it can be done you can find here.

Ensure that you have the following tools packaged:

• iPhoneOS16.2.sdk
• iPhoneOS17.5.sdk
• iPhoneSimulator16.2.sdk
• iPhoneSimulator17.5.sdk
• MacOSX13.1.sdk
• MacOSX14.5.sdk
• XcodeDefault14.2.xctoolchain.darwin
• XcodeDefault15.4.xctoolchain.darwin

NOTE: Complete list of needed packages see link

After obtain packages with sdks and toolchains you make it available via HTTP. The easiest way to do these is to run Python HTTP server on local machine. For example,

    cd <path_where_packages_located>
    python -m http.server

It starts local web server that available at http://localhost:8000.

Setup all needed packages via

    DM_PACKAGES_URL=<url_where_package_located> ./server/scripts/standalone/setup-standalone-env.sh

If you run local HTTP server from previous step replace <url_where_package_located> with http://localhost:8000. It's download packages, unpack it to correct folder and generate .env file with correct pathes.

Local Extender's application

There are two ways to obtain Extender's jars:

1. Download ready-to-use jars from public repo. See instructions here (step 5).
2. Build jars locally. See instruction here.

As result you should have 2 jars in ./server/apps/ folder: extender.jar and manifestmergetool.jar.

Run

To run stand-alone Extender instance use folowing script:

    ./server/scripts/standalone/service-standalone.sh start

Script takes commad as 1st argument. Command can be one of the following:

• start - start new Extender instance
• stop - stop already running Extender instance
• restart - stop and start Extender instance from the scratch

If you want to use different Spring profile you can pass it via 2nd argument. For example,

    ./server/scripts/standalone/service-standalone.sh start standalone-dev

Note: all Spring profiles should be located in ./server/configs/ folder.

As a result Extender should start and start listening 9010 port (that port set by default). E.g. Extender can be reached via http://localhost:9010. Logs of extender can be found in ./server/app/logs/ folder.

If you want to use other port (not 9010) you can change property server.port in ./server/configs/application-standalone-dev.yml.
