Maven eating compiler errors?
Hi,
I'm having trouble where Maven is not showing compiler errors as one
would expect.
Take the following:
```
# Create a basic 'hello world' project
$ mvn archetype:generate -DgroupId=com.mycompany.app
-DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false
$ cd my-app/
# Add a syntax error
$ sed -i 's/println/printl/g' src/main/java/com/mycompany/app/App.java
# Try to compile
$ mvn package
```
I get the following:
...
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile
(default-compile) on project my-app: Compilation failure
[ERROR] /home/bourke/tmp/my-app/src/main/java/com/mycompany/app/App.java:[11,18]
error: cannot find symbol
[ERROR] -> [Help 1]
...
It doesn't show me what symbol is wrong. Compare with the default javac output:
$ javac src/main/java/com/mycompany/app/App.java
src/main/java/com/mycompany/app/App.java:11: error: cannot find symbol
System.out.printl( "Hello World!" );
^
symbol: method printl(String)
location: variable out of type PrintStream
1 error
Obviously much more useful.
Any help much appreciated.

Ok I understand what you mean now.
Adding the stanza listed at
http://maven.apache.org/plugins/maven-compiler-plugin/usage.html has
given me better output:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.0:compile
(default-compile) on project my-app: Compilation failure
[ERROR] /home/bourke/tmp/my-app/src/main/java/com/mycompany/app/App.java:[11,19]
cannot find symbol
[ERROR] symbol: method printl(java.lang.String)
[ERROR] location: variable out of type java.io.PrintStream
[ERROR] -> [Help 1]
Thanks very much :)

If you use version 3.0 of maven-compiler-plugin it should give you better
info if you use JDK 1.6+. You need to pin down the version of the plugin in
the pom.
