JarCastingmule4-jar-size-reducer-maven-plugin
maven plugin which reduces the mule-application.jar files created by mule4 applications
Usage:
Add following section to your pom.xml (maybe with up-to-date versions):
...
<build>
...
<plugin>
<groupId>io.github.c-a-services</groupId>
<artifactId>mule4-jar-size-reducer-maven-plugin</artifactId>
<executions>
<execution>
<id>compress-jar</id>
<phase>package</phase>
<goals>
<goal>jar-compress</goal>
</goals>
</execution>
</executions>
<configuration>
<stripMatchingFiles>
<stripMatchingFile>^repository/.*\.pom$</stripMatchingFile>
</stripMatchingFiles>
</configuration>
</plugin>
...
<pluginManagement>
...
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.1.1</version>
</plugin>
<plugin>
<groupId>io.github.c-a-services</groupId>
<artifactId>mule4-jar-size-reducer-maven-plugin</artifactId>
<version>2019.10.3</version>
</plugin>
</plugins>
</pluginManagement>
</build>
...
and then during building the repository/**/jar files will be replaced by placeholders. (you may set the plugin/execution section into a profile to not replace the jar content always). Another possibility is to call mvn package -Dcompress-jar-skip=true
Add this profile to the pom.xml
<profile>
<id>deploy-to-cloud-z-os</id>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>download-all-dependencies-for-refill</id>
<!-- phase is clean to hook into:
https://mantis.retail-sc.com/view.php?id=878065
(validate requires maven >= 3.3.3)
-->
<phase>clean</phase>
<goals>
<!-- resolve as many artifacts before running jar-refill to use normal dependency resolution
and not internal downloadArtifact via org.twdata.maven.mojoexecutor.MojoExecutor -->
<goal>resolve</goal>
<goal>tree</goal>
</goals>
</execution>
</executions>
<configuration>
<verbose>true</verbose>
</configuration>
</plugin>
<plugin>
<groupId>io.github.c-a-services</groupId>
<artifactId>mule4-jar-size-reducer-maven-plugin</artifactId>
<executions>
<execution>
<id>refill-jar</id>
<!-- phase is clean to hook into:
https://mantis.retail-sc.com/view.php?id=878065
(validate requires maven >= 3.3.3)
-->
<phase>clean</phase>
<goals>
<goal>jar-refill</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
</profile>
to ensure the placeholders are removed before
mvn clean mule:deploy -P deploy-to-cloud-z-os
is executed. (!) you need to execute clean and mule:deploy for above configuration.
Manual usage:
mvn io.github.c-a-services:mule4-jar-size-reducer-maven-plugin:LATEST:jar-compress
and
mvn io.github.c-a-services:mule4-jar-size-reducer-maven-plugin:LATEST:jar-refill
Known workarounds
In case go-offline fails with
Could not find artifact org.apache.maven.plugins:maven-site-plugin:jar:3.6.1
you need to add an existing version to your pluginManagement section: See (https://github.com/mulesoft/mule-maven-plugin/issues/336)
