Apache Groa could not find main class error

When I try to run apache gora compiler using ./gora goracompiler, I m getting the following error

Error: Could not find or load main class org.apache.gora.compiler.cli.GoraCompilerCLI

Before that I got JAVA_HOME not set error after that I resolved that error by setting JAVA_HOME variable

OS: Cent OS 6.5 Java version : java version "1.7.0_45" OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15) OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

Solution

  • goracompiler command expects GoraCompilerCLI to be in $GORA_HOME/gora-compiler-cli/target/classes/

    Check you have gora-compiler-cli/target/classes/java/org/apache/gora/compiler/cli/GoraCompilerCLI.class or the .jar from the module gora-compiler-cli in the classpath.

    If not, compile the module with:

    mvn package -pl gora-compiler-cli
