A flag whether the test class path of the project under test should be included in the class path of the pre-/post-build scripts. If set to false, the class path of script interpreter consists only of the runtime dependencies of the Maven Invoker Plugin. If set the true, the project's test class path will be prepended to the interpreter class path. Among others, this feature allows the scripts to access utility classes from the test sources of your project.

Some files are normally excluded when copying the IT projects from the directory specified by the parameter projectsDirectory to the directory given by cloneProjectsTo (e.g. .svn, CVS, *~, etc: see reference for full list). Setting this parameter to true will cause all files to be copied to the cloneProjectsTo directory.

Ensure the cloneProjectsTo directory is not polluted with files from earlier invoker runs.

Directory to which projects should be cloned prior to execution. If set to null, each integration test will be run in the directory in which the corresponding IT POM was found. In this case, you most likely want to configure your SCM to ignore target and build.log in the test's base directory. (Exception when project using invoker plugin is of maven-plugin packaging: In such case IT projects will be cloned to and executed in target/its by default.)

Whether to show debug statements in the build output.

A flag to disable the generation of build reports.

The file encoding for the pre-/post-build scripts and the list files for goals and profiles.

Additional environment variables to set on the command line.

A list of additional properties which will be used to filter tokens in POMs and goal files.

The list of goals to execute on each project. Default value is: package.

The name of an optional project-specific file that contains properties used to specify settings for an individual Maven invocation. Any property present in the file will override the corresponding setting from the plugin configuration. The values of the properties are filtered and may use expressions like ${project.version} to reference project properties or values from the parameter filterProperties.

As of 3.2.0 it is possible to put this folder in any of the ancestor folders, where properties will be inherited. This way you can provide a single properties file for a group of projects

The snippet below describes the supported properties:

invoker.updateSnapshots = true

A comma separated list of projectname patterns to run. Specify this parameter to run individual tests by file name, overriding the setupIncludes, pomIncludes and pomExcludes parameters. Each pattern you specify here will be used to create an include/exclude pattern formatted like ${projectsDirectory}/pattern. To exclude a test, prefix the pattern with a '!'. So you can just type -Dinvoker.test=SimpleTest,Comp*Test,!Compare* to run builds in ${projectsDirectory}/SimpleTest and ${projectsDirectory}/ComplexTest, but not ${projectsDirectory}/CompareTest

The JAVA_HOME environment variable to use for forked Maven invocations. Defaults to the current Java home directory.

The package name use in junit report

The local repository for caching artifacts. It is strongly recommended to specify a path to an isolated repository like ${project.build.directory}/it-repo. Otherwise, your ordinary local repository will be used, potentially soiling it with broken artifacts.

By default a build.log is created in the root of the project. By setting this folder files are written to a different folder, respecting the structure of the projectsDirectory.

mavenExecutable can either be a file relative to ${maven.home}/bin/, test project workspace or an absolute file.

The home directory of the Maven installation to use for the forked builds. Defaults to the current Maven installation.

The MAVEN_OPTS environment variable to use when invoking Maven. This value can be overridden for individual integration tests by using invokerPropertiesFile.
Since the version 3.7.0 using an alternate syntax for mavenOpts, @{...} allows late replacement of properties when the plugin is executed, so properties that have been modified by other plugins will be picked up correctly.

If enable and if you have a settings file configured for the execution, it will be merged with your user settings.

Suppress logging to the build.log file.

Number of threads for running tests in parallel. This will be the number of maven forked process in parallel. When terminated with "C", the number part is multiplied by the number of processors (cores) available to the Java virtual machine. Floating point value are only accepted together with "C".

Example values: "1.5C", "4"

A single POM to build, skipping any scanning parameters and behavior.

Exclude patterns for searching the integration test directory. This parameter is meant to be set from the POM. By default, no POM files are excluded. For the convenience of using an include pattern like *, the custom settings file specified by the parameter settingsFile will always be excluded automatically.

Include patterns for searching the integration test directory for projects. This parameter is meant to be set from the POM. If this parameter is not set, the plugin will search for all pom.xml files one directory below projectsDirectory (i.e. */pom.xml).

Starting with version 1.3, mere directories can also be matched by these patterns. For example, the include pattern * will run Maven builds on all immediate sub directories of projectsDirectory, regardless if they contain a pom.xml. This allows to perform builds that need/should not depend on the existence of a POM.

Relative path of a cleanup/verification hook script to run after executing the build. This script may be written with either BeanShell or Groovy (since 1.3). If the file extension is omitted (e.g. verify), the plugin searches for the file by trying out the well-known extensions .bsh and .groovy. If this script exists for a particular project but returns any non-null value different from true or throws an exception, the corresponding build is flagged as a failure.

Relative path of a pre-build hook script to run prior to executing the build. This script may be written with either BeanShell or Groovy (since 1.3). If the file extension is omitted (e.g. prebuild), the plugin searches for the file by trying out the well-known extensions .bsh and .groovy. If this script exists for a particular project but returns any non-null value different from true or throws an exception, the corresponding build is flagged as a failure. In this case, neither Maven nor the post-build hook script will be invoked.

List of profile identifiers to explicitly trigger in the build.

Directory to search for integration tests.

Common set of properties to pass in on each project's command line, via -D parameters.

Whether to execute Maven in quiet mode.

Base directory where all build reports are written to. Every execution of an integration test will produce an XML file which contains the information about success or failure of that particular build job. The format of the resulting XML file is documented in the given build-job reference.

Additional variables for use in the hook scripts.

Relative path of a selector script to run prior in order to decide if the build should be executed. This script may be written with either BeanShell or Groovy. If the file extension is omitted (e.g. selector), the plugin searches for the file by trying out the well-known extensions .bsh and .groovy. If this script exists for a particular project but returns any non-null value different from true, the corresponding build is flagged as skipped. In this case, none of the pre-build hook script, Maven nor the post-build hook script will be invoked. If this script throws an exception, the corresponding build is flagged as in error, and none of the pre-build hook script, Maven not the post-build hook script will be invoked.

Path to an alternate settings.xml to use for Maven invocation with all ITs. Note that the <localRepository> element of this settings file is always ignored, i.e. the path given by the parameter localRepositoryPath is dominant.

Include patterns for searching the projects directory for projects that need to be run before the other projects. This parameter allows to declare projects that perform setup tasks like installing utility artifacts into the local repository. Projects matched by these patterns are implicitly excluded from the scan for ordinary projects. Also, the exclusions defined by the parameter pomExcludes apply to the setup projects, too. Default value is: setup*/pom.xml.

Whether to show errors in the build output.

flag to enable show mvn version used for running its (cli option : -V,--show-version )

Flag used to suppress certain invocations. This is useful in tailoring the build using profiles.

Flag used to determine whether the build logs should be output to the normal mojo log.

Flag used to suppress the summary output notifying of successes and failures. If set to true, the only indication of the build's success or failure will be the effect it has on the main build (if it fails, the main build should fail as well). If streamLogs is enabled, the sub-build summary will also provide an indication.

Location of a properties file that defines CLI properties for the test.

No description.

Only invoke maven projects if their sources have been modified since they were last built. Only works in conjunction with cloneProjectsTo.

Force a check for missing releases and updated snapshots on remote repositories. This is passed to the invoked maven projects (it is the same as if you were to use the -U, --update-snapshots flag on the command line).

Write test result in junit format.
