Has anyone ever ran into this problem or a similar one? I looked at their HelloWorld app example and I do not see anything different from my current implementation.
Moreover, I really only need their default configuration. Here is the source code of the EnvironmentConfiguration currently in the version 1. Of course you will have to test and validate if upgrading the version will not cause any incompatibility at runtime. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Asked 3 years ago. String[] files Scans the directory looking for source files to be compiled. String compiler Choose the implementation for this particular task.
String v Keyword list to be appended to the -g command-line switch. File destDir Set the destination directory into which the Java source files should be compiled.
String encoding Set the Java source file encoding name. String errorProperty The property to set on compilation failure. String forkExec Sets the name of the javac executable. String memoryInitialSize The initial size of the memory for the underlying VM if javac is run externally; ignored otherwise.
String memoryMaximumSize The maximum size of the memory for the underlying VM if javac is run externally; ignored otherwise. File nhDir Set the destination directory into which the generated native header files should be placed. String release Sets the version to use for the --release switch that combines source , target and setting the bootclasspath.
String v Value of the -source command-line switch; will be ignored by all implementations except modern, jikes and gcj gcj uses -fsource. String target Sets the target VM that the classes will be compiled for. File tmpDir Where Ant should place temporary files. String updatedProperty The property to set on compilation success. Methods inherited from class org. Method Detail getDebugLevel public java. Returns: value of debugLevel. Legal values are none or a comma-separated list of the following keywords: lines, vars, and source.
If debuglevel is not specified, by default, :none will be appended to -g. If debug is not turned on, this attribute will be ignored.
Parameters: v - Value to assign to debugLevel. Returns: value of source. If you use this attribute together with jikes or gcj, you must make sure that your version of jikes supports the -source switch. Legal values are 1. This is either the name specified with the executable attribute or the full path of the javac compiler of the VM Ant is currently running in - guessed by Ant.
You should not invoke this method if you want to get the value of the executable command - use getExecutable for this. Defaults to the build. If fork has been set to true, the result will be extJavac and not classic or java1. Package org. Object org. ProjectComponent org. Task org. MatchingTask org. Javac All Implemented Interfaces: java. This task can take the following arguments: sourcedir destdir deprecation classpath bootclasspath extdirs optimize debug encoding target depend verbose failonerror includeantruntime includejavaruntime source compiler release Of these arguments, the sourcedir and destdir are required.
Check that all required attributes have been set and nothing silly has been entered. The classpath to use when loading the compiler implementation if it is not a built-in one. Gets the destination directory into which the java source files should be compiled. Gets whether or not the java runtime should be included in this task's classpath.
Gets the destination directory into which the generated native header files should be placed. Gets the version to use for the --release switch that combines source , target and setting the bootclasspath. Whether package-info. Indicates whether source should be compiled with debug information; defaults to off. The Sun compiler also allows more control over the boot classpath using the -X and -J-X attributes. Since Ant 1.
For example:. The OpenJDK project has provided the javac compiler as an open source project. The output of this project is a javac. The argument needs to be given to the runtime system of the javac executable, so it needs to be prepended with a -J , for example:.
On compilation, if the. Prior to Ant 1. With Ant 1. This logic turned out to lead to Ant not recompiling package-info. The sourcepath to use. Location of bootstrap class files. See below for using the -X and -J-X parameters for specifying the bootstrap classpath.
The classpath to use, given as a reference to a path defined elsewhere. The sourcepath to use, given as a reference to a path defined elsewhere. The bootstrapclasspath to use, given as a reference to a path defined elsewhere. Encoding of source files. Note : gcj doesn't support this option yet. Indicates whether source should be compiled with debug information.
If set to off , -g:none will be passed on the command line for compilers that support it for other compilers, no command line argument will be used. If set to true , the value of the debuglevel attribute determines the command line argument.
Keyword list to be appended to the -g command-line switch. Legal values are none or a comma-separated list of the following keywords: lines , vars , and source. No; ignored when debug is false or any implementation other than modern , javac1.
Indicates whether source should be compiled with optimization. Note that this flag is just ignored by Sun's javac since JDK 1. Enables dependency tracking for compilers that support this jikes and classic. Whether to include the Ant run-time libraries in the classpath.
It is usually best to set this to false so the script's behavior is not sensitive to the environment in which it is run. No; defaults to yes , unless build. Whether to include the default run-time libraries from the executing JVM in the classpath. Note : In some setups the run-time libraries may be part of the "Ant run-time libraries" so you may need to explicitly set includeAntRuntime to false to ensure that the Java run-time libraries are not included. Complete path to the javac executable to use in case of fork is yes.
The initial size of the memory for the underlying JVM, if javac is run externally. Examples: , k , or 80m. The maximum size of the memory for the underlying JVM, if javac is run externally; ignored otherwise. Java language features accepted by compiler, as specified by the -source command-line switch. Valid feature versions are 1. The attribute will be ignored by all implementations prior to javac1.
