Leonid Ilyevsky commented on MCOMPILER-158:
-------------------------------------------
I see this problem is fixed in the plugin version 3.1.
> Symbol name should be displayed during compiler error using Java 7

> Key: MCOMPILER-158
> URL: https://jira.codehaus.org/browse/MCOMPILER-158
> Project: Maven Compiler Plugin
> Issue Type: Improvement
> Affects Versions: 2.3.2
> Reporter: Raghuram
>
> Got to install Java 7. Tried it out on some of our source code which uses
> maven. Worked fine till there was a compilation error.
> {code}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
> (default-compile) on project my-app: Compilation failure
> [ERROR] \work\my-app\src\main\java\com\mycompany\app\App.java:[11,45] error:
> cannot find symbol
> [ERROR] -> [Help 1]
> {code}
> I am ok with the error, but which _symbol_ does it fail to find? Tried the
> same thing with Java 6.
> {code}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
> (default-compile) on project my-app: Compilation failure
> [ERROR] \work\my-app\src\main\java\com\mycompany\app\App.java:[11,45] cannot
> find symbol
> [ERROR] symbol : variable Dummy
> [ERROR] location: class com.mycompany.app.App
> [ERROR] -> [Help 1]
> {code}
> I can clearly see which variable is not found. So what has changed?
> Tried *javac* on the class. Output with java 7.
> {code}
> javac App.java
> App.java:11: error: cannot find symbol
> System.out.println( "Hello World!" + Dummy);
> ^
> symbol: variable Dummy
> location: class App
> 1 error
> {code}
> Output with java 6.
> {code}
> javac App.java
> App.java:11: cannot find symbol
> symbol : variable Dummy
> location: class com.mycompany.app.App
> System.out.println( "Hello World!" + Dummy);
> ^
> 1 error
> {code}
> We can see a couple of differences with Java 7 compiler compared to Java 6.
> * Location does not show complete package, just the class
> * Symbol and location now come after the line which has the error, instead of
> before.
> * An additional "error" word comes before the error message
> Essentially there is a change in compiler output in case of errors, which I
> guess needs a corresponding maven compiler change.
