Deploy stage failed: FileMagic v0.7.1 error

Question

I built a simple CodePipeline for a SpringBoot Java application with 3 steps:  
  
1. Source: get the source from GitHub  
2. Build: a jar file  
3. Deploy: to an AWS Elastic Beanstalk instance  
  
1 and 2 steps successfully pass while Deploy step fails. The only error I see in eb-activity.log:

```
01_configure_application.sh] : Activity execution failed, because: Executing: /usr/bin/unzip -o -d /var/app/staging /opt/elasticbeanstalk/deploy/appsource/source_bundle

```

My Buildspec:

```
build:
  commands:
      - mvn -P ci --settings settings.xml install -DskipTests
artifacts:
  files:
     - microservices/my-service/target/my-service.jar
```

If I deploy this jar directly to AWS Elastic Beanstalk using AWS Web Interface, it works perfectly.  
  
Please, help me. I'm ready to share any other config on demand.

Answer

The problem was in artifact's sub-folders, it's impossible to use an artifact location as in my Buildspec:

```
artifacts:
  files:
     - microservices/my-service/target/my-service.jar
```

the only correct way is **folder/myapp.jar**, for example:

```
artifacts:
  files:
     - target/my-service.jar
```

so you should specify **outputDirectory** in your maven config if it is different.
