QUESTION
I am experimenting with MapStruct where I want to have a mapper use another mapper to combine multiple objects into one. For my tests I have three domain objects, DomainObject1, DomainObject2 and DomainObject3. I want to convert DomainObject1 to a DTO, TransferObjectA, which has a field containing a second DTO, TransferObjectB, that is constructed using DomainObject2 and DomainObject3.
I have two mappers, one that converts DomainObject2 and DomainObject3 to TransferObjectB which ignores a field in DomainObject2 so it isn't converted:
ANSWER
Answered 2022-Mar-12 at 06:28MapStruct currently can only use other mappers with a single source parameter. There is an open feature request mapstruct/mapstruct#2081 about this functionality.
What you could do is to use a wrapper object instead of multiple source parameters.

QUESTION
MapStruct generates code at compile-time and it should not require any runtime dependencies:
How is MapStruct different from other bean mapping tools?
Unlike most other bean mapping tools, MapStruct doesn’t work at runtime but is a compile-time code generator.
Generating mapping code at build time has many advantages:
- Excellent performance, as no reflection or byte code generation at runtime is needed; the generated code contains plain method invocations, just as if the mapper was hand-written
- No runtime dependencies, making MapStruct a great solution for Android applications
Which dependency scope should be used in a Maven project? Should MapStruct be included as a provided dependency?
...ANSWER
Answered 2022-Feb-12 at 08:23The org.mapstruct:mapstruct dependency contains the needed annotations to signal the org.mapstruct:mapstruct-processor what to do.
It also contains the Mappers factory that is used when using the default component model. Therefore, the scope of org.mapstruct:mapstruct depends on the component model that you are using:
If you are using this component model then you need org.mapstruct:mapstruct during runtime if you are using Mappers or if you have dependencies between different mappers.
In theory you can use the default component model and instantiate your own mappers. However, dependencies between mappers are still going to use Mappers, unless you have instantiated your mapper in MyMapper.INSTANCE somehow already, then MapStruct will use MyMapper.INSTANCE to get the instance of the MyMapper. This would mean that you can still use the same scope as the other component models (see below for more information)
In this case you do not need org.mapstruct:mapstruct during runtime and you can use true with provided.
With Gradle this would be compileOnly dependency.
Note: Be careful when using Spring Boot and provided the Spring Boot maven plugin will still include the org.mapstruct:mapstruct dependency in the final provided jar. You'll need to ignore it by configuring the Spring Boot Maven plugin.

This is a follow-up of a previous question about using a Python dictionary to generate a list of files to include as input for a single step. In this case, I'm interested in merging BAM files for a single sample that have been generated by mapping FASTQ files from multiple runs.

ANSWER
Answered 2022-Jan-04 at 03:10In rule combine_bams, when using lambda expression you will need to provide the values of all {} wildcards. Right now there is only run information provided. One way to fix this is to include kwarg allow_missing=True to expand:

Install Mapper
You can use Mapper like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Mapper component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
