classpath

问题 Is it possible to convert project .classpath file to pom.xml after converting a simple web application project to maven project? Because if my project uses many jars and I want to convert it to maven then I will do configure->convert to maven but then it is not possible to add all the jars dependencies in pom.xml manually. So is there any tool to convert this. 回答1: First there is no tool to do such things. The problem is usually that you have a larger number of dependencies which you don't

问题 In Eclipse, using the CCW plug-in, I want to load a clojure file into a REPL. The problem is that I have an import statement for one of my own java classes, but apparently it is not in my classpath. (ns my-clj-ns (:import [alg.gen Enumerator])) Do I have to make jars out of every class that I want use/test in a Clojure REPL? Currently, trying to load my clj into a REPL results in an error: "Load file in Clojure REPL" did not complete normally. Please see the log for more information. java

问题 I'm using a Java Agent and Javassist to add some logging to some JDK classes. Essentially when the system loads some TLS classes, Javassist will add some additional bytecode to them to help me debug some connection problems. Here's the problem, given this class is included in the agent jar: package com.something.myagent; public class MyAgentPrinter { public static final void sayHello() { System.out.println("Hello!"); } } In my agent's transform method, let's say I tried to invoke that class

问题 In the run configuration of eclipse, you are provided with a set of default variables that you can use in the VM arguments, like container_path and env_var . What I want to access is a classpath variable, M2_REPO , but can't see a way of doing this. I need to specify a javaagent in the VM arguments, which requires a path to a jar file. This jar file lives in the maven repository, but I can't find a way of specifying the path to the maven repository using the already configured M2_REPO

问题 I'm playing with Rhino, and I've had success using Java classes from the stdlib, but not from Java code I compiled here. For example, this works fine: print(new java.util.Date()); But with NanoHTTPD (single .java file, no namespace, same folder), I'm having no luck at all: js> new Packages.NanoHTTPD() js: "<stdin>", line 4: uncaught JavaScript runtime exception: TypeError: [JavaPackage NanoHTTPD] is not a function, it is object. at <stdin>:4 I'm sure it's something simple. What am I missing?

问题 My problem is that I've put a well-formed properties file in my classpath and told grails to look for the properties file in my classpath, but the properties in the file aren't overriding the existing ones. In my config.groovy I have the lines: grails.config.locations = [ "classpath:${appName}-config.properties", "file:./${appName}-config.properties"] // verified that appName is being used. It prints out classpath:XXX-config.properties, as expected, where XXX is my appname. println "grails
