Hi all, Whenever I try to build jar file for pig after making some updates to the pig code, I these lines in the build result
[echo] svnString svn: This client is too old to work with working copy '/PigHome/src/org/apache/pig/backend/hadoop/executionengine/mapReduceLayer'. You need [echo] to get a newer Subversion client, or to downgrade this working copy. [echo] See http://subversion.tigris.org/faq.html#working-copy-format-change [echo] for details. Even though the build is successful and the jar file is created. When I try to run pig, I get this error: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/pig/Main Caused by: java.lang.ClassNotFoundException: org.apache.pig.Main at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Caused by: java.io.IOException: invalid header field at java.util.jar.Attributes.read(Attributes.java:389) at java.util.jar.Manifest.read(Manifest.java:234) at java.util.jar.Manifest.<init>(Manifest.java:52) at java.util.jar.JarFile.getManifestFromReference(JarFile.java:160) at java.util.jar.JarFile.getManifest(JarFile.java:146) at sun.misc.URLClassPath$JarLoader$2.getManifest(URLClassPath.java:693) at java.net.URLClassLoader.defineClass(URLClassLoader.java:221) at java.net.URLClassLoader.access$000(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) ... 6 more Could not find the main class: org.apache.pig.Main. Program will exit. I tried reverting to the original code from trunk for all the java files that I have changed in org.apache.pig.backend.hadoop.executionengine.mapReduceLayer, but it did not fix the problem. I have not actually experiencing this problem before. I was able to add code and build the pig jar file and use it. I am not sure what triggered it. I also tried to move to the most reacent build from the trunk and once I add my code I started getting the same error. I would really appreciate any idea to how to fix this problem. Thanks Iman
