| |
| /* This is a smart javac wrapper primarily used when building the OpenJDK, |
| though other projects are welcome to use it too. But please be aware |
| that it is not an official api and will change in the future. |
| (We really mean it!) |
| |
| Goals: |
| |
| ** Create a state file, containing information about the build, so |
| that incremental builds only rebuild what is necessary. Also the |
| state file can be used by make/ant to detect when to trigger |
| a call to the smart javac wrapper. |
| |
| This file is called bin/javac_state (assuming that you specified "-d bin") |
| Thus the simplest makefile is: |
| |
| SJAVAC=java -cp .../tools.jar com.sun.tools.sjavac.Main |
| SRCS=$(shell find src -name "*.java") |
| bin/javac_state : $(SRCS) |
| $(SJAVAC) src -d bin |
| |
| This makefile will run very fast and detect properly when Java code needs to |
| be recompiled. The smart javac wrapper will then use the information in java_state |
| to do an efficient incremental compile. |
| |
| Previously it was near enough impossible to write an efficient makefile for Java |
| with support for incremental builds and dependency tracking. |
| |
| ** Separate java sources to be compiled from java |
| sources used >only< for linking. The options: |
| |
| "dir" points to root dir with sources to be compiled |
| "-sourcepath dir" points to root dir with sources used only for linking |
| "-classpath dir" points to dir with classes used only for linking (as before) |
| |
| ** Use all cores for compilation by default. |
| "-j 4" limit the number of cores to 4. |
| For the moment, the sjavac server additionally limits the number of cores to three. |
| This will improve in the future when more sharing is performed between concurrent JavaCompilers. |
| |
| ** Basic translation support from other sources to java, and then compilation of the generated java. |
| This functionality might be moved into annotation processors instead. |
| Again this is driven by the OpenJDK sources where properties and a few other types of files |
| are converted into Java sources regularily. The javac_state embraces copy and tr, and perform |
| incremental recompiles and copying for these as well. META-INF will be a special copy rule |
| that will copy any files found below any META-INF dir in src to the bin/META-INF dir. |
| "-copy .gif" |
| "-copy META-INF" |
| "-tr .prop=com.sun.tools.javac.smart.CompileProperties |
| "-tr .propp=com.sun.tools.javac.smart.CompileProperties,java.util.ListResourceBundle |
| "-tr .proppp=com.sun.tools.javac.smart.CompileProperties,sun.util.resources.LocaleNamesBundle |
| |
| ** Control which classes in the src,sourcepath and classpath that javac is allowed to see. |
| Again, this is necessary to deal with the source code structure of the OpenJDK which is |
| intricate (read messy). |
| |
| "-i tools.*" to include the tools package and all its subpackages in the build. |
| "-x tools.net.aviancarrier.*" to exclude the aviancarrier package and all its sources and subpackages. |
| "-x tools.net.drums" to exclude the drums package only, keep its subpackages. |
| "-xf tools/net/Bar.java" // Do not compile this file... |
| "-xf *Bor.java" // Do not compile Bor.java wherever it is found, BUT do compile ABor.java! |
| "-if tools/net/Bor.java" // Only compile this file...odd, but sometimes used. |
| |
| ** The smart javac wrapper is driven by the modification time on the source files and compared |
| to the modification times written into the javac_state file. |
| |
| It does not compare the modification time of the source with the modification time of the artifact. |
| However it will detect if the modification time of an artifact has changed compared to the java_state, |
| and this will trigger a delete of the artifact and a subsequent recompile of the source. |
| |
| The smart javac wrapper is not a generic makefile/ant system. Its purpose is to compile java source |
| as the final step before the output dir is finalized and immediately jared, or jmodded. The output |
| dir should be considered opaque. Do not write into the outputdir yourself! |
| Any artifacts found in the outputdir that javac_state does not know of, will be deleted! |
| This can however be prevented, using the switch --permit-unidentified-artifacts |
| This switch is necessary when build the OpenJDK because its makefiles still write directly to |
| the output classes dirs. |
| |
| Any makefile/ant rules that want to put contents into the outputdir should put the content |
| in one of several source roots. Static content that is under version control, can be put in the same source |
| code tree as the Java sources. Dynamic content that is generated by make/ant on the fly, should |
| be put in a separate gensrc_stuff root. The smart javac wrapper call will then take the arguments: |
| "gensrc_stuff src -d bin" |
| |
| The command line: |
| java -cp tools.jar com.sun.tools.sjavac.Main \ |
| -i "com.bar.*" -x "com.bar.foo.*" \ |
| first_root \ |
| -i "com.bar.foo.*" \ |
| second_root \ |
| -x "org.net.*" \ |
| -sourcepath link_root_sources \ |
| -classpath link_root_classes \ |
| -d bin |
| |
| Will compile all sources for package com.bar and its subpackages, found below first_root, |
| except the package com.bar.foo (and its subpackages), for which the sources are picked |
| from second_root instead. It will link against classes in link_root_classes and against |
| sources in link_root_sources, but will not see (try to link against) sources matching org.net.* |
| but will link against org.net* classes (if they exist) in link_root_classes. |
| |
| (If you want a set of complex filter rules to be applied to several source directories, without |
| having to repeat the the filter rules for each root. You can use the explicit -src option. For example: |
| sjavac -x "com.foo.*" -src root1:root2:root3 ) |
| |
| The resulting classes are written into bin. |
