Join them; it only takes a minute: Sign up Unable to find a javac compiler com.sun.tools.javac.Main is not on the classpath error up vote 2 down vote favorite 1 I am trying to run java application and I am getting following error, Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not eclipse set java_home point to the JDK I have gone through many SO questions and found solution is JAVA_HOME should be point to JDK, not JRE. Then I have tried to print JAVA_HOME in command prompt, I had set this JAVA_HOME from my computer->properties->env variables -> system vars as below, I had also added new variable in eclipse using preferences as, And finally I am still getting the same error. Whats wrong with JAVA_HOME ? Update : In eclipse-preferences-installed jres there is only one entry is present and which is jdk and selected, And under project properties java build path-libraries there is JRE System Liberary [jdk1.8.0_31] is used. Update 1 : C:\Program Files\Java\jdk1.8.0_31 have folder named jre. Is that jre folder causing this issue ? Can I remove this folder ? Is there is any way to add only jdk liberary in project ? java eclipse classpath share|improve this question edited Apr 16 '15 at 13:27 asked Apr 16 '15 at 8:06 fledgling 1,79611943 Pleas confirm whether you started a new console after setting variab

jdk, jre, troubleshooting | FIXING com.sun.tools.javac.Main IS NOT ON THE CLASSPATH APACHE ANT COMPILATION ERROR A few days ago I was setting my development environment up and it involved executing some Apache Ant tasks. I had installed latest Java 7, jdk1.7.0_80 to be exact and Ant 1.8.4, required by the project. Fixing https://t.co/IAW9dLdIO6.javac.Main is not on the classpath Ant compilation errorRead at: https://t.co/8nZdHREaf8— Orlando Otero (@orly_otero) July 1, 2016 Attempted to compile it and got this output: C:\Users......\src>ant Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jdk1.7.0_80\lib\tools.jar ... BUILD FAILED C:\Users\......\build.xml:xxx: The following error occurred while executing this line: .......: The following error occurred while executing .......: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jdk1.7.0_80" The first line logged by Apache Ant hints tools.jar is missing. The most common cause for this error is to have forgotten to install Java Development Kit (JDK) and/or have JAVA_HOME pointing to an actual Java Runtime Environment (JRE) installation instead of a JDK one, JRE doesn’t ship with tools.jar, but as it can be observed, the last line of previous output states JAVA_HOME is set to “C:\Program Files\Java\jdk1.7.0_80”. The problem seems to be that JDK 1.7.0_80 removed tools.jar from JAVA_HOME/lib, the solution to this issue was to install JDK 1.7.0_76 and update JAVA_HOME accordingly. ← Older Newer → Related Posts: Spring Cloud Series - Integration Testing using Spring Boot, Postgres and Docker (Aug 4, 2016) Documenting multiple REST API versions using Spring Boot, Jersey and Swagger (May 7, 2016) Spring Cloud Series - Microservices using Spring Boot, Jersey, Swagger and Docker (Apr 5, 2016) Troubleshooting high CPU usage in Java applications (Feb 11, 2016) Please enable JavaScript to view the comments powered by Disqus.
