Connect and share knowledge within a single location that is structured and easy to search. It's my sample code:. It looks like you are using Eclipse. You are better off using the JavaCompiler API , rather than attemtping to call javac directly which is in tools. Because I "knew" that I had copied the correct directory name, it took me ages to see those two different characters and fix the problem.

It must allow this assignment to preserve backwards compatibility with versions of Java SE that do not support generics. Consequently, the compiler allows the assignment of the object l , which has a raw type of List , to the object ls. The compiler generates the following warning for the definition of the method ArrayBuilder.

However, the Java programming language does not permit the creation of arrays of parameterized types. In the method ArrayBuilder. However, because of type erasure, the compiler converts the varargs formal parameter to Object[] elements.

Consequently, there is a possibility of heap pollution. To shorten or simplify the javac command line, you can specify one or more files that themselves contain arguments to the javac command except -J options.

This enables you to create javac commands of any length on any operating system. An argument file can include javac options and source filenames in any combination. The arguments within a file can be space-separated or newline-separated.

Filenames within an argument file are relative to the current directory, not the location of the argument file. Use of the ' ' character to recursively interpret files is not supported. The -J options are not supported because they are passed to the launcher, which does not support argument files.

When executing javac, pass in the path and name of each argument file with the ' ' leading character. You can create two argument files -- one for the javac options and the other for the source filenames: Notice the following lists have no line-continuation characters. The argument files can have paths, but any filenames inside the files are relative to the current working directory not path1 or path2 :. The API for annotation processors is defined in the javax. Unless annotation processing is disabled with the -proc:none option, the compiler searches for any annotation processors that are available.

The search path can be specified with the -processorpath option; if it is not given, the user class path is used. Processor on the search path. Such files should contain the names of any annotation processors to be used, listed one per line. Alternatively, processors can be specified explicitly, using the -processor option. After scanning the source files and classes on the command line to determine what annotations are present, the compiler queries the processors to determine what annotations they process.

When a match is found, the processor will be invoked. A processor may "claim" the annotations it processes, in which case no further attempt is made to find any processors for those annotations. Once all annotations have been claimed, the compiler does not look for additional processors. If any processors generate any new source files, another round of annotation processing will occur: any newly generated source files will be scanned, and the annotations processed as before.

Any processors invoked on previous rounds will also be invoked on all subsequent rounds. This continues until no new source files are generated. After a round occurs where no new source files are generated, the annotation processors will be invoked one last time, to give them a chance to complete any work they may need to do.

Finally, unless the -proc:only option is used, the compiler will compile the original and all the generated source files. To compile a set of source files, the compiler may need to implicitly load additional source files. To suppress class file generation, use -implicit:none. If this option is not specified, then the default is to automatically generate class files.

In this case, the compiler issues a warning if any such class files are generated when also doing annotation processing. The warning is not issued when the -implicit option is set explicitly. See Searching for Types. Passes option to the Java Virtual Machine JVM , where option is one of the options described on the reference page for the Java launcher. For example, -J-Xms48m sets the startup memory to 48 MB.

See java 1. Trying to customize the compiler implementation with these options and variables is risky and often does not accomplish what you want. If you must customize the complier implementation, then use the -J option to pass options through to the underlying Java launcher. Disables warning messages. This option operates the same as the -Xlint:none option. Stores formal parameter names of constructors and methods in the generated class file so that the method java.

Controls whether annotation processing and compilation are done. Specifies where to find annotation processors. If this option is not used, then the class path is searched for processors. Specifies the directory where to place the generated source files. If a class is part of a package, then the compiler puts the source file in a subdirectory that reflects the package name and creates directories as needed. Specifies the version of source code accepted.

The following values for release are allowed:. The compiler does not support assertions, generics, or other language features introduced after Java SE 1. The compiler accepts code containing generics and other language features introduced in Java SE 5. No language changes were introduced in Java SE 6. However, encoding errors in source files are now reported as errors instead of warnings as in earlier releases of Java Platform, Standard Edition.

Specifies the source code path to search for class or interface definitions. As with the user class path, source path entries are separated by colons : on Oracle Solaris and semicolons on Windows and can be directories, JAR archives, or ZIP archives. If packages are used, then the local path name within the directory or archive must reflect the package name.

Note: Classes found through the class path might be recompiled when their source files are also found. Uses verbose output, which includes information about each class loaded and each source file compiled. By default, classes are compiled against the bootstrap and extension classes of the platform that javac shipped with.

But javac also supports cross-compiling, where classes are compiled against a bootstrap and extension classes of a different Java platform implementation.

It is important to use the -bootclasspath and -extdirs options when cross-compiling. Generates class files that target a specified release of the virtual machine. Class files will run on the specified target and on later releases, but not on earlier releases of the JVM. Valid targets are 1. The default for the -target option depends on the value of the -source option:. If the -source option is not specified, then the value of the -target option is 1.

If the -source option is 1. For all other values of the -source option, the value of the -target option is the value of the -source option. Cross-compiles against the specified set of boot classes. As with the user class path, boot class path entries are separated by colons : and can be directories, JAR archives, or ZIP archives. Beginning with JDK 8, the javac compiler supports compact profiles. With compact profiles, applications that do not require the entire Java platform can be deployed and run with a smaller footprint.

The compact profiles feature could be used to shorten the download time for applications from app stores. This feature makes for more compact deployment of Java applications that bundle the JRE. This feature is also useful in small devices. The supported profile values are compact1 , compact2 , and compact3. These are additive layers. Each higher-numbered compact profile contains all of the APIs in profiles with smaller number names. Here is an example of the error message that results from attempting to compile such source code:.

In this example, you can correct the error by modifying the source to not use the Applet class. You could also correct the error by compiling without the -profile option. None of the compact profiles include the Applet class. An alternative way to compile with compact profiles is to use the -bootclasspath option to specify a path to an rt.

Using the -profile option instead does not require a profile image to be present on the system at compile time. This is useful when cross-compiling. Enables or disables specific groups of checks, where group is one of the following values: accessibility , syntax , reference , html or missing.

For more information about these groups of checks see the -Xdoclint option of the javadoc command. The -Xdoclint option is disabled by default in the javac command. The variable access specifies the minimum visibility level of classes and members that the -Xdoclint option checks. It can have one of the following values in order of most to least visible : public , protected , package and private.

For example, the following option checks classes and members with all groups of checks that have the access level protected and higher which includes protected, package and public :. The following option enables all groups of checks for all access levels, except it will not check for HTML errors for classes and members that have access level package and higher which includes package and public :.

Enables all recommended warnings. In this release, enabling all available warnings is recommended. Disables warning name. See Enable or Disable Warnings with the -Xlint Option for a list of warnings you can disable with this option.

See Enable or Disable Warnings with the -Xlint Option with the -Xlint option to get a list of warnings that you can disable with this option. Sends compiler messages to the named file. By default, compiler messages go to System. Specifies which file to read when both a source file and class file are found for a type.

If the -Xprefer:newer option is used, then it reads the newer of the source or class file for a type default. If the -Xprefer:source option is used, then it reads the source file. Use - Xprefer:source when you want to be sure that any annotation processors can access annotations declared with a retention policy of SOURCE. Control whether javac generates package-info.

Possible mode arguments for this option include the following. Collectives on Stack Overflow. Learn more. LombokProcessor cannot access class com.
