Optional Parameters

Name	Type	Since	Description
`<annotationProcessors>`	`String[]`	`0.16.0`	Qualified class names of annotation processors to run. If specified, the normal processor discovery process will be skipped. This parameter requires a 1.6 VM or above and is used only if the compliance is 1.6
`<compilerArgs>`	`List<String>`	`0.17.0`	Arguments to be passed to the compiler.
`<compilerArgument>`	`String`	`-`	Unformatted argument string to be passed to the compiler 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.
`<compilerArguments>`	`Map<String,String>`	`-`	Deprecated. 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.
`<compilerId>`	`String`	`-`	The compiler id of the compiler to use. Default value is: `jdt`. User property is: `maven.compiler.compilerId`.
`<compilerVersion>`	`String`	`-`	Version of the compiler to use, ex. "1.3", "1.5", if fork is set to true User property is: `maven.compiler.compilerVersion`.
`<copyResources>`	`boolean`	`-`	Whether all resources in the source folders should be copied to ${project.build.outputDirectory}. `true` (default) means that all resources are copied from the source folders to `${project.build.outputDirectory}`. `false` means that no resources are copied from the source folders to `${project.build.outputDirectory}`. Set this to `false` in case you want to keep resources separate from java files in `src/main/resources` and handle them using maven-resources-plugin (e.g. for resource filtering. Default value is: `true`.
`<debug>`	`boolean`	`-`	Whether to include debugging information in the compiled class files. The default value is true. Default value is: `true`. User property is: `maven.compiler.debug`.
`<deriveReleaseCompilerArgumentFromTargetLevel>`	`boolean`	`-`	Whether the `-release` argument for the Java compiler should be derived from the target level. Enabled by default. Disabling this can be useful in situations where compiling using `-release` cannot be used, e.g. when referencing internal JDK classes exported via an OSGI framework extension. In that case `<release>` should also be explicitly set to an empty value to prevent it from being inherited. Default value is: `true`.
`<encoding>`	`String`	`-`	The -encoding argument for the Java compiler User property is: `project.build.sourceEncoding`.
`<excludeResources>`	`Set<String>`	`-`	A list of exclusion filters for non-java resource files which should not be copied to the output directory.
`<excludes>`	`Set<String>`	`-`	A list of exclusion filters for the compiler.
`<executable>`	`String`	`-`	The executable of the compiler to use when fork is true. User property is: `maven.compiler.executable`.
`<extraClasspathElements>`	`Dependency[]`	`-`	Transitively add specified maven artifacts to compile classpath in addition to elements calculated according to OSGi rules. All packages from additional entries will be accessible at compile time. Useful when OSGi runtime classpath contains elements not defined using normal dependency mechanisms. For example, when Eclipse Equinox is started from application server with -Dosgi.parentClassloader=fwk parameter.
`<failOnWarning>`	`boolean`	`-`	Fail on warnings Default value is: `false`. User property is: `maven.compiler.failOnWarning`.
`<fork>`	`boolean`	`-`	Allows running the compiler in a separate process. If "false" it uses the built in compiler, while if "true" it will use an executable. Default value is: `false`.
`<generatedSourcesDirectory>`	`File`	`0.16.0`	The directory where source files generated by annotation processors will be created. This parameter requires a 1.6 VM or above and is used only if the compliance is 1.6. Default value is: `${project.build.directory}/generated-sources/annotations`.
`<includes>`	`Set<String>`	`-`	A list of inclusion filters for the compiler.
`<log>`	`String`	`-`	The format of the compiler log file. `plain` will log into a plain text file (.log), `xml` will log in xml format (.xml). If omitted, no logging into files is done. The log file name is derived from the jar file name: Example: build.properties: output.lib1/library.jar = lib1bin/ output.lib2/library.jar = lib2bin/ output.. = bin/ And a configuration: <configuration> <logEnabled>true</logEnabled> <logDirectory>${project.build.directory}/logfiles</logDirectory> <log>xml</log> </configuration> Will produce the following log files ${project.build.directory}/logfiles/@dot.xml ${project.build.directory}/logfiles/lib1_library.jar.xml ${project.build.directory}/logfiles/lib2_library.jar.xml
`<logDirectory>`	`File`	`-`	The directory where the compiler log files should be placed. For each output jar a log file will be created and stored in this directory. Logging into files is only enabled if `log` is specified. Default: `${project.build.directory}/compile-logs` Default value is: `${project.build.directory}/compile-logs`.
`<maxmem>`	`String`	`-`	maximum size, in megabytes, of the memory allocation pool, ex. "128", "128m" if fork is set to true User property is: `maven.compiler.maxmem`.
`<meminitial>`	`String`	`-`	Initial size, in megabytes, of the memory allocation pool, ex. "64", "64m" if fork is set to true User property is: `maven.compiler.meminitial`.
`<optimize>`	`boolean`	`-`	Optimize compiled code using the compiler's optimization methods Default value is: `false`. User property is: `maven.compiler.optimize`.
`<outputFileName>`	`String`	`-`	Used to control the name of the output file when compiling a set of sources to a single file. User property is: `project.build.finalName`.
`<pomOnlyDependencies>`	`PomDependencies`	`-`	Controls how additional pom dependencies are handled that are not used in the dependency computation of the bundle. This can be used to have compile only dependencies, e.g. annotations that are only have class or source retention. Possible values are: consider (default) - pom dependencies not used already are added to the compile class path ignore - pom dependencies not used already are ignored wrapAsBundle - currently not used (but for future enhancements) treated as if 'consider' was given Default value is: `consider`.
`<proc>`	`String`	`0.16.0`	If `only` is specified, the annotation processors will run but no compilation will be performed. If `none` is specified, annotation processors will not be discovered or run; compilation will proceed as if no annotation processors were found. By default the compiler must search the classpath for annotation processors, so specifying `none` may speed compilation if annotation processing is not required. This parameter requires a 1.6 VM or above and is used only if the compliance is 1.6
`<release>`	`String`	`-`	The -release argument for the Java compiler User property is: `maven.compiler.release`.
`<requireJavaPackageImports>`	`boolean`	`-`	Since OSGi R7 it is allowed to import java.* packages as well and considered good practice. This option controls if Tycho enforces this rule. Default value is: `false`.
`<requireJREPackageImports>`	`Boolean`	`-`	Deprecated. Whether a bundle is required to explicitly import non-java.* packages from the JDK. This is the design-time equivalent to the equinox runtime option osgi.compatibility.bootdelegation. See also: requireJavaPackageImports

`<useJDK>`	`ToolchainProvider$JDKUsage`	`-`	Which JDK to use for compilation. Default value is SYSTEM which means the currently running JDK. If BREE is specified, MANIFEST header `Bundle-RequiredExecutionEnvironment` is used to define the JDK to compile against. In this case, you need to provide a toolchains.xml configuration file. The value of BREE will be matched against the id of the JDK toolchain elements in `toolchains.xml`. If the BREEs version is 9 or later and the ID did not match any element, the version of the BREE will be matched against the version of the JDK toolchain elements. Example: <toolchains> <toolchain> <type>jdk</type> <provides> <id>JavaSE-11</id> <version>11</version> </provides> <configuration> <jdkHome>/path/to/jdk/11</jdkHome> </configuration> </toolchain> </toolchains> The default value of the bootclasspath used for compilation is `<jdkHome>/lib/;<jdkHome>/lib/ext/;<jdkHome>/lib/endorsed/` .
