maven default lifecycle phases


Maven build life cycle is divided into build phases, and the build phases are divided into build goals. Maven default lifecycle handles everything related to compiling and packaging your project.

Maven default lifecycle phases:

validate validate the project is correct and all necessary information is available.
initialize initialize build state, e.g. set properties or create directories.
generate-sources generate any source code for inclusion in compilation.
process-sources process the source code, for example to filter any values.
generate-resources generate resources for inclusion in the package.
process-resources copy and process the resources into the destination directory, ready for packaging.
compile compile the source code of the project.
process-classes post-process the generated files from compilation, for example to do bytecode enhancement on Java classes.
generate-test-sources generate any test source code for inclusion in compilation.
process-test-sources process the test source code, for example to filter any values.
generate-test-resources create resources for testing.
process-test-resources copy and process the resources into the test destination directory.
test-compile compile the test source code into the test destination directory
process-test-classes post-process the generated files from test compilation, for example to do bytecode enhancement on Java classes. For Maven 2.0.5 and above.
test run tests using a suitable unit testing framework. These tests should not require the code be packaged or deployed.
prepare-package perform any operations necessary to prepare a package before the actual packaging. This often results in an unpacked, processed version of the package. (Maven 2.1 and above)
package take the compiled code and package it in its distributable format, such as a JAR.
pre-integration-test perform actions required before integration tests are executed. This may involve things such as setting up the required environment.
integration-test process and deploy the package if necessary into an environment where integration tests can be run.
post-integration-test perform actions required after integration tests have been executed. This may including cleaning up the environment.
verify run any checks to verify the package is valid and meets quality criteria.
install install the package into the local repository, for use as a dependency in other projects locally.
deploy done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.
