Manifests recursively and appends each referenced jar file to the end of theĬlasspath, provided it is not on the classpath yet. The compiler follows the Class-Path clauses of jar files' to forbid access to type X, toĭiscourage access to type X, to forbid access to all types in package p but allow access to p/X). The default value is the value of the property "".Įntries are separated by the platform path separator.Įach directory or file can specify access rules for types between '' (e.g. This is a list of directories or jar files used to compile the source files. Vm. or .class.path in this order respectively. If no bootclasspath is specified, the compiler will infer it using the following system properties , Entries are separated by the platform path separator.Įach directory or file can specify access rules for types between ''. This is a list of directories or jar files used to bootstrap the class files used by the compiler. The recommended options have an orange background. You can control how progress is reported, or how the batch compiler is canceled, by subclassing the class .CompilationProgress. CompilationProgress progress = null // instantiate your subclass Using the static compile(String commandLine, PrintWriter outWriter, PrintWriter errWriter, CompilationProgress progress) method of the class BatchCompiler.Java -jar ecj.jar -classpath rt.jar A.java Java -jar _3.4.0.jar -classpath rt.jar A.java So it can be used as a standalone application and inside an Ant build outside of Eclipse. Processing support, a 1.6 VM is required. Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). This jar contains the batch compiler and the javac ant adapter. Search for the section JDT Core Batch Compiler. Its corresponding source is also available. Since 3.2, it is also available as a separate download. The name of the class is .batch.BatchCompiler. The batch compiler class is located in the JDT Core plug-in. Using the batch compiler Finding the batch compiler Hashtable options = myProject.getOptions(false) // get only the options set up in this project Resource filter may apply to a particular project only: When programmatically configuring options for the builder or compiler, you JDTCore Compiler Options for a complete list of compiler-related options and their defaults. For example, you can define the severity that should be used forĭifferent kinds of problems that are found during compilation. The compiler can also be configured using JDTCore Builder Options for a complete list of builder-related options and This option is set byĭefault and eliminates numerous errors. The incremental and batch builders can also be configured to only generateĪ single error when the. Entireįolders are filtered out if their name matches one of the supplied folder names Options.put(JavaCore.CORE_JAVA_BUILD_RESOURCE_COPY_FILTER, "*.ignore,META-INF/") įilenames are filtered out if they match one of the supplied patterns. Hashtable options = JavaCore.getOptions()

The following sample shows how to set up a resource filter so that files ending with '.ignore' and folders named 'META-INF', Incremental and batch builders can be configured with other options thatĬontrol which resources are copied to the output folder. On the classpath instead of the output folder. You do not have corresponding source files in a separate class file folder Is reset, you must ensure that you place all. The default for this option is to clean output folders. This is controlled using a JDT Core Builder Option (
class files in the output folder may be 'scrubbed' to ensure that no staleįiles are found.

In the case of a full batch build, all the
Additional resource files are also copied to the output folder. (along with any other incremental project builders that have been added MyProject.build(IncrementalProjectBuilder.INCREMENTAL_BUILD, myProgressMonitor) įor a Java project, this invokes the Java incremental project builder You can programmatically compile the Java source files in a project using The platform build mechanism is described in detail in Using standard platform build mechanisms. It is installed as a builder on Java projects. There is no direct API provided by theĬompiler. The JDT plug-ins include an incremental and batch Java compiler for building
