Symbol name should be displayed during compiler error using Java 7
------------------------------------------------------------------
Key: MCOMPILER-158
URL: https://jira.codehaus.org/browse/MCOMPILER-158
Project: Maven 2.x 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.
