Maven-cannot release due to local modicfications - spring-boot

Question

We have been releasing our project via Jenkins pipeline. We have a shared pipeline and the mvn release command executes with options
"'-Dgoals=deploy -DpushChanges=false -DlocalCheckout=true -DpreparationGoals=initialize ' +
'-Darguments="-Dmaven.javadoc.skip=true -Dskip.master=true" -DtagNameFormat="#{project.version}" ' +
'-Dresume=false'".
With one of recent project during maven release phase , it fails stating " Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.5.3:prepare (default-cli) on project myProject: Cannot prepare the release because you have local modifications :
14:00:25 [main] ERROR org.apache.maven.cli.MavenCli - [myProject/src/main/java/com/schema/avro/GlobalLinePlanStyle.java:modified].
This file is an autogenerated file for avro schema, which is generated by adding the below plugin in pom.xml
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro.version}</version>
<configuration>
<sourceDirectory>${project.basedir}/src/main/resources/</sourceDirectory>
<outputDirectory>${project.basedir}/src/main/java/</outputDirectory>
<fieldVisibility>PRIVATE</fieldVisibility>
<includes>
<include>**/*.avsc</include>
</includes>
<testIncludes>
<testInclude>**/*.test</testInclude>
</testIncludes>
</configuration>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>schema</goal>
</goals>
</execution>
</executions>
</plugin>
I have tried adding the explicit maven release plugin in pom.xml as below but that also have not solved the issue
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-release-plugin</artifactId>
<version>2.5.3</version>
<configuration>
<checkModificationExcludes>
<checkModificationExclude>com/schema/avro/GlobalLinePlanStyle.java</checkModificationExclude>
</checkModificationExcludes>
</configuration>
</plugin>

Answer 1

Since release:prepare expects to find "filters" in checkModificationExcludes configuration setting:
A list of additional exclude filters that will be skipped when checking for modifications on the working copy. Is ignored, when checkModificationExcludes is set.
you need to specify either path relative to project root, i.e.:
<checkModificationExcludes>
<checkModificationExclude>src/main/java/com/schema/avro/GlobalLinePlanStyle.java</checkModificationExclude>
</checkModificationExcludes>
or ant pattern:
<checkModificationExcludes>
<checkModificationExclude>**/com/schema/avro/GlobalLinePlanStyle.java</checkModificationExclude>
</checkModificationExcludes>
BTW, I do not like such setup, because in my opinion generated source files must not reside in the project structure at all, however other developers report they experience other difficulties with proper setup of avro-maven-plugin.
