Unable to set the JAVA_HOME build path
posted 3 years ago
Hello everyone. I'm currently trying to build Apache Nutch using
on CentOS 6.3. However, when I run "ant runtime", this is what I see:
$ ant runtime Buildfile: build.xml [taskdef] Could not load definitions from resource org/sonar/ant/antlib.xml. It could not be found. ivy-probe-antlib: ivy-download: [taskdef] Could not load definitions from resource org/sonar/ant/antlib.xml. It could not be found. ivy-download-unchecked: ivy-init-antlib: ivy-init: init: [mkdir] Created dir: /home/azureuser/Downloads/apache-nutch-2.1/build [mkdir] Created dir: /home/azureuser/Downloads/apache-nutch-2.1/build/classes [mkdir] Created dir: /home/azureuser/Downloads/apache-nutch-2.1/build/release [mkdir] Created dir: /home/azureuser/Downloads/apache-nutch-2.1/build/test [mkdir] Created dir: /home/azureuser/Downloads/apache-nutch-2.1/build/test/classes clean-lib: resolve-default: [ivy:resolve] :: Ivy 2.2.0 - 20100923230623 :: http://ant.apache.org/ivy/ :: [ivy:resolve] :: loading settings :: file = /home/azureuser/Downloads/apache-nutch-2.1/ivy/ivysettings.xml [taskdef] Could not load definitions from resource org/sonar/ant/antlib.xml. It could not be found. copy-libs: compile-core: [javac] Compiling 178 source files to /home/azureuser/Downloads/apache-nutch-2.1/build/classes BUILD FAILED /home/azureuser/Downloads/apache-nutch-2.1/build.xml:97: 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 "/usr/java/jdk1.7.0_17/jre" Total time: 11 seconds
However, when I run "echo $JAVA_HOME", this is what I get:
$ echo $JAVA_HOME /usr/java/jdk1.7.0_17/bin:/usr/java/jdk1.7.0_17/lib
Now, what gives? Am I not setting something correctly? Should I change something in build.xml?

JAVA_HOME variable should point to jdk folder and not to the child folders.
In your case
SCJP 5.0 OCBCD 5.0(Formerly SCBCD)

Sonar keeps downloading plugins for every analysis
