Ant Javac任务用于编译Java源文件。它扫描源目录和目标目录以编译源文件。它只有在两者之一时才编译。班级不存在或。该类早于Java文件。

如果Java源文件位于任何软件包中，则源文件应具有目录层次结构。

Attribute	Description	Required
srcdir	Source Java file.	Yes
destdir	Destination to store the class files.	No
includes	A list of patterns of files that must be included.	No
includesfile	Each line of this file is taken to be an include pattern.	No
excludes	A list of patterns of files that must be excluded.	No; defaults to default excludes or none if defaultexcludes is no
excludesfile	Each line of this file is taken to be an exclude pattern.	No
classpath	The classpath to use.	No
bootclasspath	Path of bootstrap class files.	No
extdirs	Path of installed extensions.	No
encoding	Encoding of source files.	No
nowarn	It is used to pass -nowarn switch to the compiler.	No
debug	To debug file during compilation.	No
debuglevel	Set level of debug file.	No
optimize	Indicates whether source should be compiled with optimization.	No
deprecation	Compile with with deprecation information.	No
verbose	Asks the compiler for verbose output.	No
depend	Enables dependency tracking for compilers that support it.	No
includeAntRuntime	Whether to include the Ant run-time libraries in the classpath or not.	No
fork	Whether to execute javac using the JDK compiler externally or not.	No
executable	Complete path to the javac executable.	No
memoryInitialSize	Set initial memory size.	No
memoryMaximumSize	The maximum size of the memory for the underlying JVM.	No

以下代码编译Java源文件并将类文件存储到目标目录中。

// build.xml

此示例将编译位于srcdir中的所有Java源文件，并将.class存储到destdir目录中。因为打开了调试模式，它将以调试模式编译Java源代码。

此示例将编译位于srcdir中的所有Java源文件，并将.class存储到destdir目录中。源级别为1.8，.class文件将在Jdk 1.8下运行。
