[MCOMPILER-158] Symbol name should be displayed during compiler error using Java 7 #865
Description
Raghuram opened MCOMPILER-158 and commented
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.
[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]
I am ok with the error, but which symbol does it fail to find? Tried the same thing with Java 6.
[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]
I can clearly see which variable is not found. So what has changed?
Tried javac on the class. Output with java 7.
javac App.java
App.java:11: error: cannot find symbol
System.out.println( "Hello World!" + Dummy);
^
symbol: variable Dummy
location: class App
1 error
Output with java 6.
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
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.
Affects: 2.3.2
