Package org.apache.maven.plugin.compiler

Class AbstractCompilerMojo

java.lang.Object
org.apache.maven.plugin.AbstractMojo
org.apache.maven.plugin.compiler.AbstractCompilerMojo
All Implemented Interfaces:
org.apache.maven.plugin.ContextEnabled, org.apache.maven.plugin.Mojo
Direct Known Subclasses:
CompilerMojo, TestCompilerMojo
public abstract class AbstractCompilerMojo extends org.apache.maven.plugin.AbstractMojo
TODO: At least one step could be optimized, currently the plugin will do two scans of all the source code if the compiler has to have the entire set of sources. This is currently the case for at least the C# compiler and most likely all the other .NET compilers too.
Since:
2.0

  • Field Details

    • PS

      protected static final String PS

    • source

      @Parameter(property="maven.compiler.source", defaultValue="1.7") protected String source

      The -source argument for the Java compiler.

      NOTE: Since 3.8.0 the default value has changed from 1.5 to 1.6. Since 3.9.0 the default value has changed from 1.6 to 1.7

    • target

      @Parameter(property="maven.compiler.target", defaultValue="1.7") protected String target

      The -target argument for the Java compiler.

      NOTE: Since 3.8.0 the default value has changed from 1.5 to 1.6. Since 3.9.0 the default value has changed from 1.6 to 1.7

    • release

      @Parameter(property="maven.compiler.release") protected String release
      The -release argument for the Java compiler, supported since Java9
      Since:
      3.6

    • compilerArguments

      @Parameter @Deprecated protected Map<String,String> compilerArguments
      Deprecated.
      use compilerArgs instead.

      Sets the arguments to be passed to the compiler (prepending a dash).

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

      Note that -J options are only passed through if fork is set to true.

      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.

      Note that -J options are only passed through if fork is set to true.

      Example: 
       <compilerArgs>
   <arg>-Xmaxerrs</arg>
   <arg>1000</arg>
   <arg>-Xlint</arg>
   <arg>-J-Duser.language=en_us</arg>
 </compilerArgs>
      Since:
      3.1

    • compilerArgument

      @Parameter protected String compilerArgument

      Sets the unformatted single argument string to be passed to the compiler. 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.

      Note that -J options are only passed through if fork is set to true.

    • getRequestThreadCount

      protected int getRequestThreadCount()
      try to get thread count if a Maven 3 build, using reflection as the plugin must not be maven3 api dependent

      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 build-started timestamp, then we caught a file which got changed during this build.
      Returns:
      true if at least one single dependency has changed.
