I might be misunderstanding the question, but you can compile with javac /home/MyJavaFile.java This will create MyJavaFile.class in /home You can then run it by including /home on the classpath. e.g. java -cp /home MyJavaFile If you want to generate the class file in a different directory then you can use the -d option to … Read more
Your working directory is C:\Program Files (x86)\Java\jdk1.6.0_17\bin. You are not allowed to write files here. Copy your java files to a different directory and try to compile them there. edit: You should include C:\Program Files (x86)\Java\jdk1.6.0_17\bin to your PATH environment variable. And set JAVA_PATH to C:\Program Files (x86)\Java\jdk1.6.0_17. set JAVA_PATH=”C:\Program Files (x86)\Java\jdk1.6.0_17″ set PATH=%PATH%;”C:\Program Files … Read more
First, To compile the java source file using javac you need to specify the files to compile explicitly. Example: javac PathToSourceFile/FileName.java you need not provide the path if the source file is in the current working directory. Second, whenever java encounters import abc.xyz.ClassName; it tries to resolve abc/xyz/ClassName with respect to the classpath or current … Read more
-classpath classpath Set the user class path, overriding the user class path in the CLASSPATH environment variable. If neither CLASSPATH or -classpath is specified, the user class path consists of the current directory. If the -sourcepath option is not specified, the user class path is searched for source files as well as class files. -sourcepath … Read more
On Windows… Create a batch file: for /r %%a in (.) do (javac %%a\*.java) …then execute it in the top-level source folder. On Linux… javac $(find ./rootdir/* | grep .java) Both answers taken from this thread… http://forums.oracle.com/forums/thread.jspa?threadID=1518437&tstart=15 But as others suggested, a build tool would probably prove helpful.
Use the -Werror flag. It’s not listed in the -help output, but it works. I found it through this blog entry and tested on my own code (in NetBeans with Ant). The output was: MyClass.java:38: warning: [serial] serializable class MyClass has no definition of serialVersionUID public class MyClass extends JComponent { 1 warning BUILD FAILED … Read more
This should do it (may require additional classpath elements via the -cp command line switch): javac Support/*.java Me/*.java Wrapers/*.java But if your build process gets more complex (and it will!), you should look into using Apache Ant for build automation.
The issue was that the class path needs to be set for each command (javac and java): Attempted Steps instead of going to subpackage, compile HelloWorld.java from the top_level: $javac -cp . importpackage/subpackage/HelloWorld.java compile CallPackage.java in the same way: $javac -cp . CallPackage.java run the file using the class path also: $java -cp . CallPackage … Read more
Just set the path variable to JDK bin in environment variables. Variable Name : PATH Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin But the best practice is to set JAVA_HOME and PATH as follow. Variable Name : JAVA_HOME Variable Value : C:\Program Files\Java\jdk1.8.0_31 Variable Name : PATH Variable Value : %JAVA_HOME%\bin
source: The version that your source code requires to compile. target: The oldest JRE version you want to support. Be sure to also set bootclasspath to ensure your program will work on older VMs. From the javac documentation: Cross-Compilation Example The following example uses javac to compile code that will run on a 1.6 VM. … Read more
