javac

问题 I have a Spring Product That I'm trying the use sublimLinter-javac with, and there are a few packages scattered around the project. The problem is that sublimeLinter-javac is not recognising these packages or the classes within. So I end up with 200+ errors per file making the listing pointless. How do I tell sublimeLinter where to look for these classes? 回答1: I am guessing your classpath is not pointing to the right place. You can find here an explanation on how to set project settings.

问题 I'm trying to wrap a program of mine to work with java. I tried a simple "hello world" first, -hello world.m- disp('hello world'); I used deploytool and selected java package. when it reached this line: Executing command: "javac -verbose -classpath "C:\Program Files\MATLAB\R2009b\toolbox\javabuilder\jar\javabuilder.jar" -d "C:\Users\shachar\Documents\MATLAB\deployTutorial\deployTutorial2\src\classes" "C:\Users\shachar\Documents\MATLAB\deployTutorial\deployTutorial2\src\deployTutorial2

问题 A simple example where Ent.java uses annotations and is compiled with the necessary jar dependency after which Includer.java is compiled which in turn imports Ent.java . Ent.java: import javax.persistence.Entity; import javax.persistence.Table; @Entity @Table(name="securities") public class Ent {} Includer.java: public class Includer { public void f() { Ent s = new Ent(); } } Compiling this with... javac -cp C:/apache-tomcat-7.0.59/lib/javax.persistence_2.1.0.v201304241213.jar Ent.java javac

问题 I have a hello world program called A.class . It was compiled using command javac A.java . All it does is print "hello world" . Next, I compiled using javac -g A.java . I am expecting to see line numbers, but can't see. Any idea what happened? I do see very minor differences in some kind of special characters between .class file of javac compiled, and javac -g compiled. But I can't see any line numbers. My curiosity for this is because I want to find what kind of impact line numbers may have

问题 How can i Run Annotation Processor without compiling sources using javac (Java 8 can't use Apt)? Is there any parameter for javac that could run only annotation processing without compiling all files? What i want to do by javac: Just find annotated elements and process them using defined annotation processor using -processor flag do not compile any source that doesn't have any annotation Because i want do this on Java 8 it's impossible to use Apt for this task? Or maybe it is? 回答1: The apt

问题 Consider the following returnsNull function and a call to it with a generic type: public static <T> List<T> returnNull(Class<? extends T> clazz) { return null; } public static void main( String[] args ) { List<AtomicReference<?>> l = returnNull(AtomicReference.class); } The Eclipse compiler, when set to Java 8, accepts it, but javac in Java 8 rejects it with: incompatible types: cannot infer type-variable(s) T (argument mismatch; java.lang.Class<java.util.concurrent.atomic.AtomicReference>

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: String object creation using new and its comparison with intern method I was playing around with Strings to understand them more and I noticed something that I can't explain : String str1 = "whatever"; String str2 = str1; String str3 = "whatever"; System.out.println(str1==str2); //prints true...that's normal, they point to the same object System.out.println(str1==str3); //gives true..how's that possible ? How is

问题 Adding a package-info.java file to the project, causes annotation-processors to create different output. I don't understand why this happens. I think adding the package-info.java file should not affect my build at all, because it does not contain any fancy stuff (like Annotations, etc.). It only contains the simplest package declaration: package com.example; I've managed to create a minimal project to reproduce the issue with javac only. The project has too much code to post here on

问题 Yesterday I solved a problem with an answer here on stackoverflow. But I ended up with another problem, I will try to be clear: I have a project folder in the /home/demo/Desktop/xlsToCsv/ directory where inside of it is the java file "xlsToCsv.java" and another directory with the external jars that I need in /home/demo/Desktop/xlsToCsv/jars . Now I need to compile and run my program. Yesterday I ran a command that assumed that I was already inside of /home/demo/Desktop/xlsToCsv/ , and the
