Hi,
I have a GWT project with two Maven modules and a hierarchical directory
layout (as shown in the gwt-maven-plugin documentation). When I build
from the parent directory I get a message saying "Unable to create new
cache log file" and a stack trace. The message appears just before
GwtTests are run.
The build succeeds anyway, so it's really just an annoyance, but I'd
still like to fix it. I can see that the plugin is trying to access a
sub-directory of "target" in the parent folder, however there is no
"target" in that folder.
The message doesn't appear when I build from the child module directory.
So I'm assuming it has something to do with coordinating paths between
parent and child Maven modules.
The full error message is the same as in GWT issue 6443:
http://code.google.com/p/google-web-toolkit/issues/detail?id=6443
As suggested there, I tried setting gwt.persistentunitcache from the
command line. I also tried including, in both the parent pom and the
child pom, the snippet shown there---to no avail.
In case it's relevant: my GwtTests are configured as suggested in the
gwt-maven-plugin documentation > Testing > Use GWTTestSuite padawan. (I
use a GWTTestSuite and test names follow the plugin's default naming
conventions.)
Many thanks in advance for your suggestions, greetings,
Andrew

How are you building? (what are your command-line "mvn" arguments?)
Can you show your pom.xml files?

From both the parent and the child directories, I'm doing "mvn clean install" (or "mvn -DtestTimeOut=120 clean install").
Here is the parent pom.xml:

The code for the whole project can be gotten from Github like so:
git clone https://github.com/AndrewGreen/pescadormvp.git
(I'm just finishing up the documentation... Soon I'll announcement the project on the general GWT list.)

The code for the whole project can be gotten from Github like so:
git clone https://github.com/AndrewGreen/pescadormvp.git
(I'm just finishing up the documentation... Soon I'll announcement the project on the general GWT list.)

OK got it; that's a bug.
When outFile is not absolute (which is the case by default), it should be redefined as new File(getProject().getBaseDir(), out).
A workaround should be to explicitly set 'out' to absolute path, such as ${project.build.directory}/www-test. This is what I just did on master: https://github.com/gwt-maven-plugin/gwt-maven-plugin/commit/2fa0f0065aecde5e6ced88eb5f82a6e914ec2cdb

Fantastic to see this tracked down so quickly. I can confirm that
the version of the plugin in
2fa0f0065aecde5e6ced88eb5f82a6e914ec2cdb does not produce
the error when "out" is left at its default. I can also confirm that
setting "out" to an absolute path removes the error with the current
version of the plugin (2.5.1). Thank you again for your help. Please
let me know if there's anything I can also do (maybe test additional
fixes?). Following is the working configuration from the pom of the
child module that builds as a GWT app (example/jsonp/pom.xml).
