Field Detail

• source

  @Parameter(property="maven.compiler.source",
             defaultValue="1.5")
  protected String source

  The -source argument for the Java compiler.

• target

  @Parameter(property="maven.compiler.target",
             defaultValue="1.5")
  protected String target

  The -target argument for the Java compiler.

• compilerArguments

  @Parameter
  @Deprecated
  protected Map<String,String> compilerArguments

  Deprecated. use compilerArgs instead.

  Sets the arguments to be passed to the compiler (prepending a dash) if fork is set to true.

  This is because the list of valid arguments passed to a Java compiler varies based on the compiler version.

  To pass -Xmaxerrs 1000 -Xlint -Xlint:-path -Averbose=true you should include the following:

   <compilerArguments>
     <Xmaxerrs>1000</Xmaxerrs>
     <Xlint/>
     <Xlint:-path/>
     <Averbose>true</Averbose>
   </compilerArguments>
   

  Since:

  2.0.1

• compilerArgs

  @Parameter
  protected List<String> compilerArgs

  Sets the arguments to be passed to the compiler if fork is set to true. Example:

   <compilerArgs>
     <arg>-Xmaxerrs=1000</arg>
     <arg>-Xlint</arg>
   </compilerArgs>
   

  Since:

  3.1

• compilerArgument

  @Parameter
  protected String compilerArgument

  Sets the unformatted single argument string to be passed to the compiler if fork is set to true. To pass multiple arguments such as -Xmaxerrs 1000 (which are actually two arguments) you have to use compilerArguments.

  This is because the list of valid arguments passed to a Java compiler varies based on the compiler version.

• mavenSession

  @Component
  protected MavenSession mavenSession

  We need this to determine the start timestamp of the build.

  Since:

  3.0

• convertToCompilerResult

  protected CompilerResult convertToCompilerResult(List<CompilerError> compilerErrors)

• getRequestThreadCount

  protected int getRequestThreadCount()

  try to get thread count if a Maven 3 build, using reflection as the plugin must not be maven3 api dependant

  Returns:

  number of thread for this build or 1 if not multi-thread build

• getBuildStartTime

  protected Date getBuildStartTime()

• isDependencyChanged

  protected boolean isDependencyChanged()

  We just compare the timestamps of all local dependency files (inter-module dependency classpath) and the own generated classes and if we got a file which is >= the buid-started timestamp, then we catched a file which got changed during this build.

  Returns:

  true if at least one single dependency has changed.
