Sets construction variables for the &javac; compiler.

Builds one or more Java class files. The sources may be any combination of explicit .java files, or directory trees which will be scanned for .java files. SCons will parse each source .java file to find the classes (including inner classes) defined within that file, and from that figure out the target .class files that will be created. The class files will be placed underneath the specified target directory. SCons will also search each Java file for the Java package name, which it assumes can be found on a line beginning with the string package in the first column; the resulting .class files will be placed in a directory reflecting the specified package name. For example, the file Foo.java defining a single public Foo class and containing a package name of sub.dir will generate a corresponding sub/dir/Foo.class class file. Examples: env.Java(target = 'classes', source = 'src') env.Java(target = 'classes', source = ['src1', 'src2']) env.Java(target = 'classes', source = ['File1.java', 'File2.java']) Java source files can use the native encoding for the underlying OS. Since SCons compiles in simple ASCII mode by default, the compiler will generate warnings about unmappable characters, which may lead to errors as the file is processed further. In this case, the user must specify the LANG environment variable to tell the compiler what encoding is used. For portibility, it's best if the encoding is hard-coded so that the compile will work if it is done on a system with a different encoding. env = Environment() env['ENV']['LANG'] = 'en_GB.UTF-8'

Specifies the list of directories that will be added to the &javac; command line via the -bootclasspath option. The individual directory names will be separated by the operating system's path separate character (: on UNIX/Linux/POSIX, ; on Windows).

The Java compiler.

The command line used to compile a directory tree containing Java source files to corresponding Java class files. Any options specified in the &cv-link-JAVACFLAGS; construction variable are included on this command line.

The string displayed when compiling a directory tree of Java source files to corresponding Java class files. If this is not set, then &cv-link-JAVACCOM; (the command line) is displayed. env = Environment(JAVACCOMSTR = "Compiling class files $TARGETS from $SOURCES")

General options that are passed to the Java compiler.

The directory in which Java class files may be found. This is stripped from the beginning of any Java .class file names supplied to the JavaH builder.

Specifies the list of directories that will be searched for Java .class file. The directories in this list will be added to the &javac; and &javah; command lines via the -classpath option. The individual directory names will be separated by the operating system's path separate character (: on UNIX/Linux/POSIX, ; on Windows). Note that this currently just adds the specified directory via the -classpath option. &SCons; does not currently search the &cv-JAVACLASSPATH; directories for dependency .class files.

The suffix for Java class files; .class by default.

Specifies the list of directories that will be searched for input .java file. The directories in this list will be added to the &javac; command line via the -sourcepath option. The individual directory names will be separated by the operating system's path separate character (: on UNIX/Linux/POSIX, ; on Windows). Note that this currently just adds the specified directory via the -sourcepath option. &SCons; does not currently search the &cv-JAVASOURCEPATH; directories for dependency .java files.

The suffix for Java files; .java by default.

Specifies the Java version being used by the &b-Java; builder. This is not currently used to select one version of the Java compiler vs. another. Instead, you should set this to specify the version of Java supported by your &javac; compiler. The default is 1.4. This is sometimes necessary because Java 1.5 changed the file names that are created for nested anonymous inner classes, which can cause a mismatch with the files that &SCons; expects will be generated by the &javac; compiler. Setting &cv-JAVAVERSION; to 1.5 (or 1.6, as appropriate) can make &SCons; realize that a Java 1.5 or 1.6 build is actually up to date.
