Hi Mark,
I do have Open JDK installed. The reason this is strange is because the maven
build runs fine from the command line after the project is run with Eclipse.
Other maven builds I have also run fine from the command line. For example if
I git clone apache commons math and run the build, it builds fine.
In this case I'm just creating a very minimal project with:
- pom.xml
- src/test/java/hello/HelloTest.java
When I try to run the build, it fails. If I import it into eclipse, it runs.
When I try the build from the command line again, it runs. If I create another
project with the same set of original resources, it fails all over again.
Thoughts?
Thanks again,
Ole

Hi,
I'm seeing some strange behavior with Maven 3.0.5 on Ubuntu.
BACKGROUND ===================== When I run `mvn test` the console
prints: `[ERROR] No compiler is provided in this environment.
Perhaps you are running on a JRE rather than a JDK?`
If I then open the project in Eclipse and run the test it runs
fine. Subsequently if I close Eclipse and run the test with `mvn
test` I get `BUILD SUCCESS`.
ANALYSIS ===================== I run `mvn test` on the `test2`
project, that was opened with eclipse, and I get -> `BUILD
SUCCESS`.
I then create a `test3` project, copy the pom and the src directory
from test2 to test 3. When running `mvn test` on the `test3`
project I get the error again. I included the result from my
console below:

Thoughts (Besides just open it in Eclipse :) )?
TIA, - Ole
Eclipse comes with its own compiler, so it only needs the JRE to run.
The command line needs the JDK, which you don't have installed.
Install the JDK, set $JAVA_HOME, and make sure $JAVA_HOME/bin is on
your path.
See the bottom of the following page for detailed instructions:
http://maven.apache.org/download.cgi
If you're uncomfortable about using a different Java version between
command line and Eclipse, you can always point Eclipse to the JRE
inside the JDK and use that as the default JRE for Eclipse and the IDE.
. . . just my two cents
