Cannot compile simple code
Hello fellow Maven users,
I have been trying to compile an OSGi project created using the PAX scripts.
In the source file ConsoleTaskManager.java on line 15 I have written:
System.out.println(java.lang.String.format("%s", "Why will not this
compile?"));
When I type "mvn install", I get the following error message:
[INFO] [pax:compile]
[INFO] Compiling 5 source files to
/Users/slotia/src/csplugins-slotia/work-pir-api/target/classes
[INFO] [recovering meta-data]
[INFO]

[ERROR] BUILD FAILURE

cannot find symbol
symbol : method format(java.lang.String,java.lang.String)
location: class java.lang.String
If I uncomment the offending line, the project compiles fine. I also wrote a
5-line class file with the offending line, and it compiles fine with javac.
This suggests that there probably isn't a problem with the JDK. I have tried
to clean the project, which deletes the target directory, delete the runner
directory, and delete the .m2 directory, but it still does not compile.
Here are some specs of my system:
OS: Mac OS X 10.5.6
Java: 1.5.0_16-b06-284 32-bit
Maven: 2.0.9
I am completely lost as to how to fix this. Any help would be greatly
appreciated. Thank you.

I apologize for the following typo: "If I uncomment the offending line",
which I meant to say, "If I comment the offending line".

The missing symbol method was added in Java 1.5. Maven defaults to source
level 1.4. Set your source/target to a minimum of 1.5 on the
maven-compiler-plugin, see
http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html.
