Package org.apache.maven.plugin.compiler

Class AbstractCompilerMojo

  • All Implemented Interfaces:
    org.apache.maven.plugin.ContextEnabled, org.apache.maven.plugin.Mojo
    Direct Known Subclasses:
    AbstractCompilerMojo, 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

        Since:
        2.2

      • annotationProcessors

        @Parameter

        Classpath elements to supply as annotation processor path. If specified, the compiler will detect annotation processors only in those classpath elements. If omitted, the default classpath is used to detect annotation processors. The detection itself depends on the configuration of annotationProcessors.

        Each classpath element is specified using their Maven coordinates (groupId, artifactId, version, classifier, type). Transitive dependencies are added automatically. Example: 

         <configuration>
   <annotationProcessorPaths>
     <path>
       <groupId>org.sample</groupId>
       <artifactId>sample-annotation-processor</artifactId>
       <version>1.2.3</version>

      • compilerArguments

        @Parameter
@Deprecated
protected java.util.Map<java.lang.String,​java.lang.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 java.util.List<java.lang.String> compilerArgs

        Sets the arguments to be passed to the compiler 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 java.lang.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.

      • outputFileName

        @Parameter
private java.lang.String outputFileName
        Sets the name of the output file when compiling a set of sources to a single file.

        expression="${project.build.finalName}"

        @Parameter(property="maven.compiler.debuglevel")
private java.lang.String debuglevel
        Keyword list to be appended to the -g command-line switch. Legal values are none or a comma-separated list of the following keywords: lines, vars, and source. If debug level is not specified, by default, nothing will be appended to -g. If debug is not turned on, this attribute will be ignored.
