How to build an MTA archive from the project sources

Overview

You can use one of the following two approaches for building your MTA project: - One-step build using the mbt build command - Two-step build using a combination of the mbt init and make commands.

Both methods leverage the GNU Make technology for the actual build.
If you are using the one-step approach, the tool generates a temporary build configuration file and automatically invokes the make command. The generated Makefile is then deleted at the end of the build.
The second approach allows you to generate the Makefile using the mbt init command. You can adjust the generated file according to your project needs and then build the MTA archive using the make command. In this case, we recommend that you include the generated Makefile in the project's source control management system to ensure that the same build process is applied across all the project's contributors, regardless of the build environment.

Prerequisites

  • GNU Make 4.2.1 is installed in your build environment.
  • Module build tools are installed in your build environment.

For more information, see the corresponding Download and Installation sections.

One-step build

Quick start example:

// Executes the MTA project build for the Cloud Foundry target environment.
mbt build

mbt build Generates a temporary Makefile according to the MTA descriptor and runs the make command to package the MTA project into the MTA archive.

Usage: mbt build <flags>

Flags:

Flag Mandatory /
Optional
Description                           Examples                     
-p (--platform) Optional The name of the target deployment platform.
The supported deployment platforms are:
  • cf for SAP Cloud Platform, Cloud Foundry environment
  • neo for the SAP Cloud Platform, Neo environment
  • xsa for the SAP HANA XS advanced model
If this parameter is not provided, the project is built for the SAP Cloud Platform, Cloud Foundry environment
mbt build -p=cf
-s (--source) Optional The path to the MTA project; the current path is set as the default. mbt build -p=cf -s=C:/TestProject
-t (--target) Optional The folder for the generated MTAR file. If this parameter is not provided, the MTAR file is saved in the mta_archives subfolder of the current folder. If the parameter is provided, the MTAR file is saved in the root of the folder provided by the argument. mbt build -p=cf -t=C:/TestProject
--mtar Optional The file name of the generated archive file. If this parameter is omitted, the file name is created according to the following naming convention:

<mta_application_ID>_<mta_application_version>.mtar

If the parameter is provided, but does not include an extension, the .mtar extension is added.
mbt build -p=cf --mtar=TestProject.mtar
-e (--extensions) Optional The path or paths to multitarget application extension files (.mtaext). Several extension files separated by commas can be passed with a single flag, or each extension file can be specified with its own flag. mbt build -e=test1.mtaext,test2.mtaext
or
mbt build -e=test1.mtaext -e=test2.mtaext
--strict Optional The default value is true. If set to true, the duplicated fields and fields that are not defined in the mta.yaml schema are reported as errors. If set to false, they are reported as warnings. mbt build -p=cf --strict=true
BETA   -m (--mode) Optional The possible value is verbose. If run with this option, the temporary Makefile is generated in a way that allows the parallel execution of Make jobs to make the build process faster. mbt build -m=verbose
BETA   -j (--jobs) Optional Used only with the --mode parameter. This option configures the number of Make jobs that can run simultaneously. If omitted or if the value is less than or equal to zero, the number of jobs is defined by the number of available CPUs (maximum 8). mbt build -m=verbose -j=8

 

Two-step build

Quick start example:

// Generates the `Makefile.mta` file.
mbt init 

// Executes the MTA project build for Cloud Foundry target environment.
make -f Makefile.mta p=cf

Auxiliary commands

This section is dedicated for commands that execute specific steps of the MTA build process such as project validation, build for a single module, and generation of the deployment descriptor. These commands are useful if, for example, you want to build and deploy only specific modules for testing purposes, or if you decide to tailor your own build process for packaging MTA archives. At the moment, only the commands described below are supported.

mbt mtad-gen

Usage: mbt mtad-gen <flags>

Flags:

Flag Mandatory /
Optional
Description                           Examples                     
-p (--platform) Optional The name of the target deployment platform.
The supported deployment platforms are:
  • cf for SAP Cloud Platform, Cloud Foundry environment

or
mbt mtad-gen -e=test1.mtaext -e=test2.mtaext



mbt module-build

Triggers the build process of the specified module according to the implicit or explicit build configurations in the MTA descriptor (mta.yaml file) and MTA extensions.

Usage: mbt module-build <flags>

Flags:

Flag Mandatory /
Optional
Description                           Examples                     
m (--module) Mandatory The name of the modules to build. Several modules separated by commas can be passed with a single flag, or each module can be specified with its own flag.

Notes:
  • If you specify several modules with a single flag, make sure there are no spaces between the names.
  • The tool builds the specified modules in the order defined by the build parameters in the mta.yaml file. If the specified modules depend on other modules that should be built before, run the command with the --with-all-dependencies flag or specify the required modules explicitly.
  • If the --target parameter is used, make sure that the names of the specified modules' build artifacts are unique. You can configure the build artifact name using the build-artifact-name build parameter as described here.
mbt module-build -m=my_module,another_module
or
mbt module-build -m=my_module -m=another_module
-a (--with-all-dependencies) Optional If this option is used, the tool builds all modules that the specified modules depend on in the order defined by the build parameters in the mta.yaml file before building the selected modules.
Without this option, only the selected modules are built.
mbt module-build -m=my_module,another_module -a
-s (--source) Optional The path to the folder where the project’s mta.yaml file is located; the current path is set as default. mbt module-build -m=my_module -s=C:/TestProject
-t (--target) Optional The folder where the module build results will be saved. If this parameter is not provided, the module build results are saved in the <current folder>/.<projectname>_mta_build_tmp/<module name> folder. If the parameter is provided, the build results are saved in the root of the folder provided by the argument.

Note:
If the --target parameter is used when building several modules, make sure that the names of the specified modules' build artifacts are unique. You can configure the build artifact name using the build-artifact-name build parameter as described here.
mbt module-build -m=my_module -t=C:/TestProject/build_results_tmp

The module’s build results will be saved directly in the C:/TestProject/build_results_tmp/ folder
-e (--extensions) Optional The path or paths to multitarget application extension files (.mtaext). Several extension files separated by commas can be passed with a single flag, or each extension file can be specified with its own flag. mbt module-build -m=my_module -e=test1.mtaext,test2.mtaext
or
mbt module-build -m=my_module -e=test1.mtaext -e=test2.mtaext
-g (--mtad-gen) Optional If the parameter is provided, the deployment descriptor mtad.yaml is generated by default in the current folder or in the folder configured by the --target parameter.
A module's path property in the generated mtad.yaml file points to the module's build results if this module was selected using the --modules option.

Notes:
  • The selected module list specified using the --module option, does not affect the list of modules in the resulting mtad.yaml file. The mtad.yaml file is always generated according to the default Cloud MTA Builder settings, the build-parameters configurations in the mta.yaml file (e.g. supported-platforms), and the selected target platform.
  • By default, the mtad.yaml is generated for the cf target platform. You can configure a different target plaform using the --platform option.
mbt module-build -m=my_module1,my_module2 -g
-p (--platform) Optional The name of the target deployment platform. Used only with the -g (--mtad-gen) parameter.
The supported deployment platforms are:
  • cf for SAP Cloud Platform, Cloud Foundry environment
  • neo for the SAP Cloud Platform, Neo environment
  • xsa for the SAP HANA XS advanced model
If this parameter is not provided, the mtad.yaml file is generated for the SAP Cloud Platform, Cloud Foundry environment.
mbt module-build -m=my_module1,my_module2 -g -p=neo
