Question: When running Maven in Eclipse, how do I send the console output to file?
I would like to achieve this using a pom setting or a maven plugin. I do not want to modify the run configurations or the maven system settings.
For reference, I am using Windows 7, Eclipse Luna, Java 6, Maven 3.

As per official command line options you could use -l,--log-file <arg> which provide the:
Log file where all build output will go.
As such, running:
mvn clean install -l output.log
Would not print anything to the console and automatically redirect the whole build output to the output.log file.
If you don't want to type it every time (or you actually don't want to use the command line) and you want it as default option (although rare case I would suppose), you could use new command line options behavior available since version 3.3.1 and have a .mvn folder where the concerned pom.xml file is located and a maven.config file in it simply providing the following line:
-l output.log
That is, the .mvn/maven.config file replaces MAVEN_OPTIONS just for its project, locally where it has been created, with the options it provides, not impacting other builds as per Maven settings of MAVEN_OPTIONS.
This is an IDE agnostic solution (it's a new built-in feature of Maven) and local to a project, but still not provided via simple POM editing, which cannot be achieved since the first phase of Maven default life cycle phases is validate, which:
validate the project is correct and all necessary information is available
That is, during the build, hence when the build has already started (and generated output), it validates the pom.xml file, hence too late to redirect build output at that stage based on some POM properties/plugin.

Go to run as and choose Run Configuration -> Commons -> Select a file.
This should redirect your output to the file you specified.

According to this you can try editing the ${MAVEN_HOME}/conf/logging/simplelogger.properties. I gave it a quick try and maven's output is redirected, but anything else writing to stdout (tests, for instance) still writes on the console

What about creating a fork of M2E and modifying it to read the output file for the launch config from pom.xml

回答5:
A possible solution is setting the output format in the mvn file. For example, in the directory /usr/bin, add the desired output informing the path the log will be saved at the end of exec "$JAVACMD" \ line: | tee /home/maven-log.log.
However, it only works when the maven is called by terminal line; when called by IDEs, like eclipse, this solutions does not work.
