How to deploy de-Lombok-ed sources with maven

I use Lombok in my library's code and want to use delombok'ed sources when deploying library JAR with sources to maven repository.
How to configure Maven to achieve this?
Update: Most likely, you don't need to deploy delombok'ed sources (check comments below this question for details)

Include following plugins into pom.xml's build/plugins section:
<plugin>

Jacoco coverage of unit and integration tests combined with coverageratio

In my project I use Jacoco plugin to show coverage report of unit tests,as well as integration tests,and one report which shows combined code coverage.Now I want to set coverageratio for that combined coverage,but my build is now failing because Jacoco only look for unit code coverage,not combined,which is smaller,of course, than specified report of combined.
Am I missing something in pom.xml?
Here is my configuration in pom.xml regarding to coverageratio:
<execution>
<id>default-check</id>
<goals>
<goal>check</goal>
</goals>
<configuration>
<rules>
<rule>
<element>BUNDLE</element>
<limits>
<limit>
<counter>LINE</counter>
<value>COVEREDRATIO</value>
<minimum>0.80</minimum>
</limit>
</limits>
</rule>
</rules>
</configuration>
</execution>

EDIT: Maybe more nice way is to achieve is use the same file, but let it append another test, which works for us - unit and it tests.
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>

Original text: I got inspired another post as well in this blog resulting in following code, where is visible, that is measured coverage of unit tests, integration tests, then result is merged and only for whole bundle (not individual classes) it fails, if coverage is less than 70%.

The accepted answer didn't work for me, having Jacoco write two files, one for the unit tests and other for integration tests, then merging these two files and generating the report from the single merged file as follows did:

How to copy a generated files from a dependency to the target of current project with maven?

I have tow maven projects resources-win and main-exec.I try to copy a dll file from a folder win of resources-win and copy it to target/classes, then i moved to the project number 2 main-exec and i try to copy a file 2 witch is in src/main/shcemas and the dll file of resources-win and paste them into target classes of the project resources-win
Here is the bloc of code whitch helps to copy a file to target of resources-win:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<id>copy-resources01</id>
<phase>process-classes</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
<encoding>UTF-8</encoding>
<resources>
<resource>
<directory>${basedir}/src/main/win</directory>
<includes>
<include>**/*.dll</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
Here is a part of pom.xml of the project main-exec:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-libraries</id>
<phase>generate-resources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<!-- win32 -->
<artifactItem>
<groupId>com.resources-win</groupId>
<artifactId>ressources-win</artifactId>
<version>1.0.0-SNAPSHOT</version>
<type>pom</type>
<destFileName>xdol.dll</destFileName>
<outputDirectory>${project.build.directory}/temp/schemas</outputDirectory>
</artifactItem>
</artifactItems>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>

I did like that by using an xsd file by adding to pom.xml of resources-win:
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<execution>
<id>copy-resources-xsd</id>
<phase>process-classes</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
<encoding>UTF-8</encoding>
<resources>
<resource>
<directory>${basedir}/src/main/schemas</directory>
<includes>
<include>**/*.xsd</include>
</includes>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<id>attach-artifacts</id>
<phase>package</phase>
<goals>
<goal>attach-artifact</goal>
</goals>
<configuration>
<artifacts>
<artifact>
<file>${project.build.outputDirectory}/titi.xsd</file>
<type>xsd</type>
<classifier>titi</classifier>
</artifact>
<artifact>
<file>${project.build.outputDirectory}/toto.xsd</file>
<type>xsd</type>
<classifier>toto</classifier>
</artifact>
</artifacts>
</configuration>
</execution>
</executions>
</plugin>
Then into the pom.xml of main-exec i added:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-libraries</id>
<phase>generate-resources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>groupId of resources-win</groupId>
<artifactId>artifactId of resources-win</artifactId>
<version>${resources-win.version}</version>
<type>xsd</type>
<classifier>toto</classifier>
<destFileName>toto.xsd</destFileName>
<outputDirectory>${project.build.directory}/tmp/schemas</outputDirectory>
</artifactItem>
</artifactItems>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>true</overWriteSnapshots>
</configuration>
</execution>
</executions>
</plugin>
I added also the the pom.xml of main-exec the dependency of resources-win.

My mixed Scala/Java Maven project doesn't compile

I have a mixed Scala/Java project that doesn't compile well.
The problem arises when Java code is trying to call Scala code in the same package.
Of course, I have the standard layout:
src/main/java
src/main/scala
src/test/java
src/test/scala
I've looked at other similar Stackoverflow questions but this question is a little outdated. This other question doesn't help either.
I have also followed the scala-maven-plugin documentation page.

I have tried unsuccessfully to follow this blog post.
IDEA project with Scala plugin imported from the pom.xml can compile and run my project successfully.
What is the right way of doing it?
Does the Java code gets compiled twice? First by the Scala plugin and the by the Java plugin?.

Here is a working example of pom.xml :

Problem 1
At first I thought the problem was due to using a modern version of the maven-compiler-plugin. I was using version 3.0 instead of 2.0.2.
The solution has been:
- Remove the maven-compiler-plugin
- Add this setting: incremental
Finally my pom.xml is this:
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.1.6</version>
<configuration>
<recompileMode>incremental</recompileMode>
<args>
<arg>-deprecation</arg>
<arg>-explaintypes</arg>
<arg>-target:jvm-1.7</arg>
</args>
</configuration>
<executions>
<execution>
<id>scala-compile-first</id>
<phase>process-resources</phase>
<goals>
<goal>add-source</goal>
<goal>compile</goal>
</goals>
</execution>
<execution>
<id>scala-test-compile</id>
<phase>process-test-resources</phase>
<goals>
<goal>add-source</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
Problem 2
Another problem I was experiencing is this:
<dependencies>
<dependency>
<groupId>org.json4s</groupId>
<artifactId>json4s-native_${scala.version}</artifactId>
<version>3.2.9</version>
</dependency>
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>${scala.version}.4</version>
</dependency>
</dependencies>
<properties>
<scala.version>2.10</scala.version>
</properties>
This make this solved problem arise:
https://issues.scala-lang.org/browse/SI-5733
Probably it was using an old version of the Scala compiler.
The solution has been to rename scala.version to scala.major, as this property has a special meaning.

In order to get the scala-maven-plugin to respect Java 1.8, but still allow mixed compilation of java and scala, we use this:
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
<executions>
<execution>
<id>default-compile</id>
<phase>none</phase>
</execution>
</executions>
</plugin>
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<recompileMode>incremental</recompileMode>
</configuration>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
</plugin>
...

I add blow code at pom.xml file <build> block and working good!

maven-jaxb2-plugin VS jaxb2-maven-plugin for multiple schemas

I have multiple xsd schemas that I want to unmarshall into different packages under the same folder target/generated-sources/xjc. I tried both plugins and both seem to work fine with these 2 configurations but in case of maven-jaxb2-plugin the eclipse plugin keeps generating classes indefinitely (because of the forceRegenerate = true) but if I don't specify forceRegenerate it won't generate the second and third set of classes at all when I run mvn clean package Are there any issues with my configuration?

General advice: specify your packages in bindings.xjb rather than in different executions with individual generatePackages.
<jxb:bindings schemaLocation="common1.xsd" node="/xsd:schema">
<jxb:schemaBindings>
<jxb:package name="mypackage.commonclasses"/>
</jxb:schemaBindings>
</jxb:bindings>
generatePackage does not really work well with multiple schemas.
And please file a bug in
https://java.net/jira/browse/MAVEN_JAXB2_PLUGIN
citing the problem with the multiple schemas and Eclipse. I'll take a look into it.
