问题 I am putting together a dev environment for a Java program and after the first try of my Ant build scripts I got this error: Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-6-openjdk/lib/tools.jar While the path to the jdk is correct, the tools.jar really wasn't there. Is it actually supposed to be there or did I get some config/installation thing wrong? 回答1: It's there on my machine. I'm running Sun JDK 1.6.0_21 on Windows XP SP3. Are you sure you have the JDK? Is it

Is it safe to distribute tools.jar along with a Java application bundle?

问题 Although tools.jar is not a component in JRE, but it comes with all major implementations of JDK such as Oracle JDK and OpenJDK. Not being standard component of JRE means that when I distribute a Java application which uses tools.jar , I have to distribute it along with the application bundle OR include it in classpath. My questions are: Does tools.jar contain platform-dependent components that prevent it from being distributed across different platforms (Windows/Linux/OSX)? We already know

问题 When I run ant it says: Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar Buildfile: build.xml does not exist! Build failed What package can I use to download the file required > C:\Program Files\Java\jre6\lib\tools.jar I just downloaded this one: jre-6u19-windows-i586-s.exe but unfortunately it appears that it was not on it... 回答1: Java ships in 2 versions: JRE & SDK (used to be called JDK) The JRE in addition to not containing the compiler, also

What exactly is “tools.jar” in the Android SDK?

问题 So, I've been trying to build a project in LibGDX for about 10 hours now. In case you'r unfamiliar, LibGDX is one of those platforms where you specify a project directory at the start, along with any required SDKs and then when you're ready to start coding it will generate a project for you. Anyway, I've been having a problem where every time I try to build it fails with the single error message: Execution failed for task :core:compileJava. Could not find tools.jar I'm guessing "tools.jar" is

ToolProvider.getSystemJavaCompiler() always returning null using jdk

由 拟墨画扇 提交于 2019-12-08 04:16:22
问题 I read all the posts regarding this problem and no solution works for me, I get always null . I use JRE and put the tools.jar in the lib directory, added it to the build path but when I want to jump to declaration Eclipse wants to jump into rt.jar (?) what I totally don't understand. Could that be the reason that I get only null ? How can I configure that correctly? What are the criteria for getSystemJavaCompiler() to return null? Preferences screenshot 回答1: JRE is the Java Runtime

Why does using the Java Attach API fail on linux? (even though maven build completes)

问题 I've been using the Java Attach API (part of tools.jar) to attach to a running java process, and shut it down from within. It works perfectly on Windows. However when trying to actually execute the attach code when running on linux I get a java.lang.NoClassDefFoundError with the following stack trace for the cause... java.lang.ClassNotFoundException:com.sun.tools.attach.VirtualMachine... java.net.URLClassLoader$1.run(URLClassLoader.java:202) java.security.AccessController.doPrivileged(Native

Java compiler at Runtime

由 房东的猫 提交于 2019-12-05 05:42:59
In my current project, I need to compile java code at runtime (in the background to process input from the user). This works fine with tools.jar in the classpath. However, not all users of my program have JDK installed on their system. Some of them only have JRE and in that case there is no java compiler available at runtime. I can solve that problem by including tools.jar from Sun as a part of my tool. But tools.jar is very big (>12 MB). The problem is that I have to include the large jar file, although I am interested only in a small fraction of the functionality provided by this jar. Is it

how to add tools.jar as a “dynamic dependency” in sbt. is it possible?

由 限于喜欢 提交于 2019-12-05 02:17:04
问题 i need to use tools.jar in my project, but there is not much sense to package it in the jar, since the user already have it. so, is it possible to use it as a "dynamic dependency"? meaning, i want my code to compile by using tools.jar file found in my JAVA_HOME , but i don't want it to get packaged with it. i can make sure to add it to the classpath with double activation at runtime with the user's JAVA_HOME used instead. for example: object Main1 extends App { val myjar = Main1.getClass
