# Estimate: 18s # alias mvncc = 'mvn clean compiler:compile compiler:testCompile -nsu -T 1C' # Maven NSU (no snapshot update) # Maven full build without snapshot update # running in parallel. Terminal: # Maven CC (src compile + test compile) # Double compilation for both source code # and test code running in parallel. I make the summary as Bash alias, so that they can be executed easily in your So I think we reach our limit now :) Summary Mvn clean -nsu compiler:compile compiler:testCompiler -T 1C -amd -pl 'm7' For example, if I changeĪ class called Foo.java, and rebuild the Maven as mentioned before, the Specified in option -pl and all the dependent ones (flag -amd). If you want the build to be even faster, you shoud build just the project

You look on your clock on the wall, therefore it’s called Wall-Clock Only 10s + some overhead for parallelization. The total CPU time stays the same (40s), but the time that passed for YOU is Simple clean, compile, install, build commands mvn compile Compiles source code and stores classes to target/classes mvn validate Validates project mvn test Runs tests mvn clean Deletes target directory mvn clean package Compiled code is packaged to WAR/JAR/deb etc mvn clean install Install the artifact in local repository(.

You start the build with 4 threads, so the total time of 40s gets divided by So you only have one process, which (in your example) takes 40s. What is “Wall-Clock” time in Maven? Here’s an answer from Stack Overflow:īy default (without -T), Maven builds all modules sequentially rather than This option is very useful when you only want to So skipping them will make the build much faster:Īs you can see, the time for building each module is longer, but the Wall-Clock Actual Build Time Without Tests ModuleĪs you can see, the JavaScript modules are using much more time than any other

#MVN CLEAN INSTALL DSKIPTESTS COMMAND HOW TO#

We’ll try to understand why the build is slow, which are the real pain pointsĪnd, how to speed it up using better Maven commands. In our team, we have a big codebase with hundred of thousands of lines of code.īuilding it locally is a huge pain.
