tools.jar

问题 I am trying to get a project to run using Maven in Eclipse, but I am getting this error below. The tools.jar is in the JDK's lib folder, but tools-1.6.jar doesn't seem to exist on my computer. I am using the JDK 1.7 and my JAVA_HOME is pointing to that folder (as is my eclipse.ini ) Anyone know where I can get this file or what I might be doing wrong? The container 'Maven Dependencies' references non existing library C:\Users\sejohnson\.m2\repository\com\sun\tools\1.6\tools-1.6.jar 回答1: The

问题 I am trying to create an application that can compile a provided .java file during runtime. I understand that there is a programmatical compiler available within the tools.jar of the JDK. However, I cannot guarantee that the user of the application has JDK. I have attempted to package tools.jar within the application and reference it as a library. This seems to work within the Eclipse IDE when I have tools.jar added into the Bootstrap Entries of the classpath. When exporting the application

问题 I have a maven project in Eclipse where I am using some hadoop libraries (hadoop-common, hadoop-auth, hadoop-hdfs) and these bring in a dependency on jdk.tools. When I check this project out on a different machine, it works fine, but on mine the pom.xml complains about "missing artifact jdk.tools:jdk:tools:jar:1.6". I can fix this by adding a dependency manually and specifying the file on my local drive (eg "${JAVA_HOME}/../lib/tools.jar") but I would like to understand why it works on one

问题 The ':javap' command in the scala 2.9.1 console need the tools.jar (from JDK6) in the 'classpath'. From cmd-line it could be done with '-cp' argument or CLASSPATH environment variable. How to do the same for scala console that invoked from SBT with the 'console' and 'console-quick' commands? 回答1: Long answer, that might help you elsewhere. If I want to know about something in SBT, I inspect it: > inspect console [info] Task: Unit [info] Description: [info] Starts the Scala interpreter with

问题 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

问题 I'm having trouble using tools.jar present in jdk1.8.0_121/lib/tools.jar . My $JAVA_HOME is set to: # echo $JAVA_HOME /usr/local/java/jdk1.8.0_121 The path to tools.jar is : # ls /usr/local/java/jdk1.8.0_121/lib/tools.jar /usr/local/java/jdk1.8.0_121/lib/tools.jar And I use the following java executable to run the code: /usr/local/java/jdk1.8.0_161/bin/java But, when I access the VirtualMachine class, it throws Caused by: java.lang.ClassNotFoundException: com.sun.tools.attach.VirtualMachine

问题 I'm referring to the jar with the Compiler Tree API, referred to here It can be found here but not for download. Maybe I could download it from there with downthemall, but what are the alternatives? 回答1: The Javadoc for the tree API comes with the official JDK documentation. The JDK documentation can be downloaded from: http://www.oracle.com/technetwork/java/javase/downloads/index.html#docs Inside the downloaded ZIP, look in /jdk/api/javac/tree directory. 回答2: Prunge was right, but they have
