How can I print to the console while executing a mvn command (in a phase/goal), but not using Maven Antrun plugin?
Why I reject Antrun solutions:
- The overhead in code to print a single message is massiv.
- The output is no formated like maven output
- I cannot attach a severity to the message (e.g. DEBUG, INFO, ERROR, etc)
Currently an Ant-echo looks like this (see line with "hello world"):
[INFO] --- maven-antrun-plugin:1.7:run (default) @ ejpd-alertmanager-ear ---
[WARNING] Parameter tasks is deprecated, use target instead
[INFO] Executing tasks
main:
[echo] hello world
[INFO] Executed tasks
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
However, I expect it to look like this (see line with "hello world").
[INFO] --- maven-antrun-plugin:1.7:run (default) @ ejpd-alertmanager-ear ---
[WARNING] Parameter tasks is deprecated, use target instead
[INFO] Executing tasks
[INFO] hello world
[INFO] Executed tasks
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
I'm positive, I am missing something here, since I cannot be the first to raise this demand. Thank you for any smart hint.
I haven't tried this myself but there is a plugin here which may help:
http://code.google.com/p/maven-echo-plugin/
You should try the Maven Echo plugin:
<plugin>
<groupId>com.soebes.maven.plugins</groupId>
<artifactId>maven-echo-plugin</artifactId>
<version>0.1</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>echo</goal>
</goals>
</execution>
</executions>
<configuration>
<echos>
<echo>This is the Text which will be printed out.</echo>
</echos>
</configuration>
</plugin>
Or furthermore take a deeper look into the integration test of the plugin.
which is available via Maven Central. BTW: If you have further requests/improvements just file in an issue.
You can use Björn Ekryd's Echo Maven Plugin, which is published in Maven Central.
It has a normal amount of XML required for a Maven plugin, the output is formatted like the other Maven log lines, and you can assign a severity level to your message (default is INFO).
<plugin>
<groupId>com.github.ekryd.echo-maven-plugin</groupId>
<artifactId>echo-maven-plugin</artifactId>
<version>1.2.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>echo</goal>
</goals>
<configuration>
<message>war has changed</message>
<level>INFO</level>
</configuration>
</execution>
</executions>
</plugin>
[INFO] --- maven-war-plugin:2.4:war (default-war) @ mymodule ---
[INFO] Packaging webapp
[INFO] Processing war project
[INFO]
[INFO] --- echo-maven-plugin:1.2.0:echo (default) @ mymodule ---
[INFO] war has changed
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
Also, this plugin has 95% code coverage, which is pretty cool.
You can use Groovy Maven Plugin for this.
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>2.0</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>
log.info('Test message: {}', 'Hello, World!')
</source>
</configuration>
</execution>
</executions>
</plugin>
The configuration above will produce the following output:
[INFO] Test message: Hello, World!
