Stu created MASSEMBLY-875:
-----------------------------
Summary: Maven 3.x is about 10x slower than 2.6
Key: MASSEMBLY-875
URL: https://issues.apache.org/jira/browse/MASSEMBLY-875
Project: Maven Assembly Plugin
Issue Type: Bug
Reporter: Stu
In all our java projects, we have a fairly basic assembly configuration,
something like this:
{code:java}
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<manifest>
<mainClass>org.x.x.x</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>{code}
They all take about 10x longer with any 3.x.x version of the maven assembly
plugin than the 2.6 version.
This has been noticed by others:
[https://stackoverflow.com/questions/9009232/what-sort-of-configuration-issues-or-problems-might-make-maven-assembly-plugin-g/24519615#24519615]
But not reported as a bug that I could find.
Although I could only justify "Minor" for the priority, this is really is a
blocker for us moving to 3.x.x
The upgrade is just not worth taking your build from < 10 sec to > 50 sec.
