clover2:setup

Full name:

com.atlassian.maven.plugins:maven-clover2-plugin:2.5.0:setup

Description:

This mojo is to be used mainly for incremental instrumentation and compilation of Java source code.

NB: This does not, nor should it, run in a forked lifecycle. This mojo should certainly *not* be called during a release build. This mojo instruments your source and test files to ${build.directory}/clover/src-optimized and test-src-optimized respectively. These directories are then set as the project's source and test source directories that subsequently get compiled by the compiler MOJO.

Attributes:

  • Requires a Maven 2.0 project to be executed.
  • Requires dependency resolution of artifacts in scope: test.
  • Binds by default to the lifecycle phase: process-sources.

Required Parameters

Name Type Since Description
cloverMergeDatabase String - The location of the merged clover database to create when running a report in a multimodule build.
Default value is: ${project.build.directory}/clover/cloverMerge.db.
cloverOutputDirectory String - The directory where the Clover plugin will put all the files it generates during the build process. For example the Clover plugin will put instrumented sources somewhere inside this directory.
Default value is: ${project.build.directory}/clover.
localRepository ArtifactRepository - Local maven repository.
pluginArtifacts List - List of all artifacts for this Clover plugin provided by Maven. This is used internally to get a handle on the Clover JAR artifact.

Note: This is passed by Maven and must not be configured by the user.
project MavenProject - The Maven project instance for the executing project.

Note: This is passed by Maven and must not be configured by the user.

Optional Parameters

Name Type Since Description
cloverDatabase String - The location of the Clover database.
distributedCoverage DistributedCoverage - The configuration for distributed coverage collection by Clover. If present, default values will be used and coverage will be collected across JVMs. Optional nested elements (and their defaults) of distributedCoverage are:
  • host - the host name of the JVM running the tests. default: localhost
  • port - the port that Clover can bind to in the host JVM. default: 1198
  • numClients - the number of clients expected to attach to the Test JVM. The test JVM will wait until numClients have connected before continuing. default: 0
  • timeout - the amount of time to wait for a response from a remote JVM before shunning it. default: 5000
  • retryPeriod - the amount of time a client should wait between reconnect attempts. default: 1000
encoding String - The character encoding to use when parsing source files.
excludes Set - The list of file to exclude from the instrumentation.
flushInterval int - When the Clover Flush Policy is set to "interval" or threaded this value is the minimum period between flush operations (in milliseconds).
Default value is: 500.
flushPolicy String - The Clover flush policy to use. Valid values are directed, interval and threaded.
Default value is: threaded.
includes Set - The list of file to include in the instrumentation. Defaults are **.java which are overwritten if <includes> is set by the user
includesAllSourceRoots boolean - Whether the Clover plugin should instrument all source roots (ie even generated sources) or whether it should only instrument the main source root.
Default value is: false.
includesTestSourceRoots boolean - Whether the Clover plugin should instrument test source roots.
Default value is: true.
instrumentation String - The level to instrument to. Valid values are 'method' or 'statement'. Default is 'statement'. Setting this to 'method' greatly reduces the overhead of enabling Clover, however limited or no reporting is available. The current use of setting this to method is for Test Optimization only.
jdk String - Whether the Clover instrumentation should use the Clover jdk14, jdk15 or jdk16 flags to parse sources. Valid values are 1.4, 1.5 and 1.6 .
license String - The full Clover license String to use. If supplied, this certificate will be used over licenseLocation. NB. newline chars must be preserved. A trial Clover license can be generated here.
licenseLocation String - A Clover license file to be used by the plugin. The plugin tries to resolve this parameter first as a resource, then as a URL, and then as a file location on the filesystem. A trial Clover license can be generated here.
methodContexts Map - Specifies the custom method contexts to use for filtering specific methods from Clover reports. e.g. 
<main>public static void main\(String args\[\]\).*</main>
will define the context called 'main' which will match all public static void main methods.
singleCloverDatabase boolean - If true, then a single cloverDatabase will be used for the entire project. This flag will be ignored if a custom cloverDatabase location is specified.
Default value is: false.
skip boolean - A flag to indicate not to run clover for this execution. If set to true, Clover will not be run.
Default value is: false.
snapshot File - The location to store the clover snapshot file. This file needs to persist between builds to enable Clover's build optimization feature. If not specified, the snapshot will be stored next to the cloverDatabase.
staleMillis int - Sets the granularity in milliseconds of the last modification date for testing whether a source needs reinstrumentation.
Default value is: 0.
statementContexts Map - Specifies the custom statement contexts to use for filtering specific statements from Clover reports. e.g. 
<log>^LOG\..*</log>

defines a statement context called "log" which matches all LOG statements.

useFullyQualifiedJavaLang boolean - Use the fully qualified package name for java.lang.* classes.
Default value is: true.
waitForFlush boolean - If true we'll wait 2*flushInterval to ensure coverage data is flushed to the Clover database before running any query on it.

Note: The only use case where you would want to turn this off is if you're running your tests in a separate JVM. In that case the coverage data will be flushed by default upon the JVM shutdown and there would be no need to wait for the data to be flushed. As we can't control whether users want to fork their tests or not, we're offering this parameter to them.


Default value is: true.
