Compiling Error in Maven

Question

Seeing compilation error in maven. Checked and tried all the workarounds which i got from google and stack* sites. but still i couldnt resolve.

Installed maven 3.3.3 and its supported version of java which is 1.7. Please note i haven't set JAVA_HOME, M2 and M2_HOME environment variables. but still takes the path.

Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00)

Java version: 1.7.0_85, vendor: Oracle Corporation

Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-573.3.1.el6.x86_64", arch: "amd64", family: "unix"

yes. package hg-groupid; /** * Hello world! * */ public class App { public static void main( String[] args ) { System.out.println( "Hello World!" ); } } — divakar.scm, Aug 31 '15 at 06:59

Going out on a limb here... but does line 1 of App.java contain the following package definition:

package hg-groupid;

If so, the problem relates to the hyphen you have in the package name - Java identifiers are not permitted to contain a hyphen in their name - you may wish to change this to an underscore.

Thanks alot. Define value for property 'package': whether this is an issue? can you tell what is the property for? – divakar.scm Aug 31 '15 at 07:06
Not quite sure what you're asking... `package` is a reserved word in Java, so you shouldn't try to create a property named that. If you're asking what should the first line be - probably something like `package hg_groupid` (but you'll also need to change the name of the directory in which the App.java resides - to `hg_groupid`) – Crollster Aug 31 '15 at 07:09
Thanks, solved my problem. Created my package through the interactive prompt using mvn archetype:generate. Guess it wouldn't be too difficult to prevent the user from specifying package names with hyphens there... (it didn't complain at all there) – Igor Jul 19 '17 at 09:43
