      • skipInvocation

        @Parameter(property="invoker.skip",
           defaultValue="false")
private boolean skipInvocation
        Flag used to suppress certain invocations. This is useful in tailoring the build using profiles.
        Since:
        1.1

      • suppressSummaries

        @Parameter(defaultValue="false")
protected boolean suppressSummaries
        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.

      • streamLogs

        @Parameter(property="invoker.streamLogs",
           defaultValue="false")
private boolean streamLogs
        Flag used to determine whether the build logs should be output to the normal mojo log.

      • localRepositoryPath

        @Parameter(property="invoker.localRepositoryPath",
           defaultValue="${settings.localRepository}")
private java.io.File localRepositoryPath
        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.

      • projectsDirectory

        @Parameter(property="invoker.projectsDirectory",
           defaultValue="${basedir}/src/it/")
private java.io.File projectsDirectory
        Directory to search for integration tests.

      • reportsDirectory

        @Parameter(property="invoker.reportsDirectory",
           defaultValue="${project.build.directory}/invoker-reports")
private java.io.File reportsDirectory
        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.
        Since:
        1.4

      • disableReports

        @Parameter(property="invoker.disableReports",
           defaultValue="false")
private boolean disableReports
        A flag to disable the generation of build reports.
        Since:
        1.4

      • cloneProjectsTo

        @Parameter(property="invoker.cloneProjectsTo")
private java.io.File cloneProjectsTo
        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.
        Since:
        1.1

      • cloneAllFiles

        @Parameter(defaultValue="false")
private boolean cloneAllFiles
        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.
        Since:
        1.2

      • cloneClean

        @Parameter(defaultValue="true")
private boolean cloneClean
        Ensure the cloneProjectsTo directory is not polluted with files from earlier invoker runs.
        Since:
        1.6

      • pom

        @Parameter(property="invoker.pom")
private java.io.File pom
        A single POM to build, skipping any scanning parameters and behavior.

      • pomIncludes

        @Parameter
private java.util.List<java.lang.String> pomIncludes
        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.

      • pomExcludes

        @Parameter
private java.util.List<java.lang.String> pomExcludes
        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.

      • setupIncludes

        @Parameter
private java.util.List<java.lang.String> setupIncludes
        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.
        Since:
        1.3

      • goals

        @Parameter
private java.util.List<java.lang.String> goals
        The list of goals to execute on each project. Default value is: package.

      • invoker

        @Component
private org.apache.maven.shared.invoker.Invoker invoker

        @Component

      • toolchainManagerPrivate

        @Component
private org.apache.maven.toolchain.ToolchainManagerPrivate toolchainManagerPrivate

      • selectorScript

        @Parameter(property="invoker.selectorScript",
           defaultValue="selector")
private java.lang.String selectorScript
        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.
        Since:
        1.5

      • preBuildHookScript

        @Parameter(property="invoker.preBuildHookScript",
           defaultValue="prebuild")
private java.lang.String preBuildHookScript
        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.

      • postBuildHookScript

        @Parameter(property="invoker.postBuildHookScript",
           defaultValue="postbuild")
private java.lang.String postBuildHookScript
        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.

      • testPropertiesFile

        @Parameter(property="invoker.testPropertiesFile",
           defaultValue="test.properties")
private java.lang.String testPropertiesFile

           defaultValue="false")
private boolean noLog
        Suppress logging to the build.log file.

      • logDirectory

        @Parameter
private java.io.File logDirectory
        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.
