Read properties from pom.xml from Java
Hi
I have been tossed into a maven controlled project. We run our junit tests from Eclipse and also on our build server. When ever they are run, some maven magic happens so that username/password/driver/url for the dabase is correctly set for the user pc or the buildserver. However I need to make a small helper class for my junit tests that wipes the database and loads some testdata on the database for every junit test.
The username/password/driver/url for the database is set in the pom.xml file by maven. How do I read these values from my Java helper class?
Best regards
Søren

Are you doing this from within a JUnit test launched by either
maven-surefire-plugin or maven-failsafe-plugin?
If so then the reason you cannot read the properties is because surefire is
cleaning up the system properties in order to encourage keeping your code
decoupled from maven... (which actually is a good thing... good build tools
should not lock you in, and should encourage you to do things in a way where
you are not locked into your build tool... that way you will continue to use
that build tool because it is the best, and not because you are locked in)
There are really two ways to solve your problem...
1. Read the connection details from a file on the classpath, e.g. in your
unit test you would do something like:
public class MyTest {
...
private final Properties properties = new Properties();
@Before
public void setUp() throws IOException {
properties.load(getClass().getResourceAsStream("/test.properties"));
...
}
...
}
you then enabling filtering on the properties file which you put in
src/test/resources, e.g. for the above example you would put your properties
in ${basedir}/src/test/resources/test.properties
For most of my projects, I get fed up enabling filtering on specific files,
so I just have this in our corporate root pom:
<resources>
<resource>
<filtering>false</filtering>
<directory>${basedir}/src/main/resources/verbatim</directory>
</resource>
<resource>
<filtering>true</filtering>
<directory>${basedir}/src/main/resources/filtered</directory>
</resource>
</resources>
<testResources>
<testResource>
<filtering>false</filtering>
<directory>${basedir}/src/test/resources/verbatim</directory>
</testResource>
<testResource>
<filtering>true</filtering>
<directory>${basedir}/src/test/resources/filtered</directory>
</testResource>
</testResources>
And I would but test.properties in ${basedir}/src/test/resources/filtered
2. Read the connection details from the System properties... this requires
telling Surefire/Failsafe to set the system properties, see
http://maven.apache.org/plugins/maven-surefire-plugin/examples/system-properties.html

My way would have test.properties with the following contents:
db.driver=oracle.jdbc.OracleDriver
db.url=${database.url}
db.username=${database.username}
db.password=${database.password}
By having the test resource filtered, the properties from the pom/settings
will be substituted into the resource when it is copied to
target/test-classes by maven-resources-plugin
If you decide to move away from maven, all you have to do is modify how the
test.properties file gets copied...
and the bonus is that you can debug the property substitution as you can
look at target/test-classes/test.properties to verify that it is being
substituted correctly.

Well it seems that I use 2.4.3, so I have changed it to the now deprecated way also. It still gives me null values... :(
I think my problem is elsewhere now, I do not think maven gets activated when I run my junit tests. I will look into this issue now.

That's almost exactly how I do it. The differences are:
- I'm still using surefire 2.4.2
- Due to the older version I use the (now) deprecated method of defining
system properties in surefire (<systemProperties> instead of
<systemPropertyVariables>)
How and where are you trying to access the properties? In some JUnit test which is executed by the maven surefire plugin via System.getProperty("db.url")? That definitely works for me.
However, Stephen's comments about locking you to maven this way sounds reasonable. His approach is probably the better one. But I don't know yet how these properties could be used in pom.xml for plugin configuration. Do they get imported by maven somehow?

Sorry, I missed one important point: you have to "export" your properties to become system properties. Do this by configuring the surefire plugin as described here:
http://maven.apache.org/plugins/maven-surefire-plugin/examples/system-properties.html
I just double checked it, this way it works.

It's as Anders wrote already. If you want to use the same property names in settings.xml and pom.xml you have to put them in a profile, that's how I do it and it works. The profile could be <activeByDefault> if you prefer.
So your settings.xml could look like this:
<settings>
<profiles>
<profile>
<id>someProf</id>
<activation>
<activeByDefault/>
</activation>
<properties>
<database.url>someUrl</database.url>
</properties>
</profile>
</profiles>
</settings>
And your pom.xml would be this:
<project>
...
<properties>
<database.url>someDummyValue</database.url>
</properties>
</project>
Now reading the properties via System.getProperty("database.url") shoud work.

Sure, that doesn't work. The properties you want to be set in settings.xml
(either globally or locally), you just skip those in your pom.
However, you should clearly state in the pom what properties are required. I
think I would use one set of properties to be defined in settings.xml and
then reference those when setting the properties in the project. IMO that's
a little bit more clear.
Like this:
<properties>
<database.driver>oracle.jdbc.OracleDriver</database.driver>
<database.url>${oracle.db.url}</database.url>
<database.username>${oracle.db.username}</database.username>
<database.password>${oracle.db.password}</database.password>
</properties>

RE: Read properties from pom.xml from Java
Posted by be...@external.icw-global.com.
According to Maven's documentation here
http://maven.apache.org/pom.html#Properties, this should work (I didn't
try it):
settings.xml:
<settings>
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<database.driver>oracle.jdbc.driver.OracleDriver</database.driver>
<database.url>jdbc:oracle:thin:@myhome:1521:orcl</database.url>
pom.xml:
<properties>
<db.driver>oracle.jdbc.OracleDriver</db.driver>
<db.url>${settings.database.url}</db.url>
I don't know if the profile comes into play in this case or if the whole
path is needed like 'settings.profiles.profile....'. Just try it.

But I do use the @Before annotation, and I was planning to call my database cleanup from here. But my problem is that the database properties are not accessible to me (I think), and they are managed by maven (are they not?).

Søren,
after reading this post from you I know that my suggestion is not what you
want, since you already have it (starting the sql-maven-plugin once before
all tests). If you need something to be done before every single test,
you'll have to use Junit's '@Before' annotated methods. If you need some
advice here, we should make this outside this list since this is no Maven
issue at all.

RE: Read properties from pom.xml from Java
Posted by Søren Krogh Neigaard <So...@systematic.com>.
Thank you all for your answers
I tried adding the following to my pom.xml
<properties>
<database.driver>oracle.jdbc.OracleDriver</database.driver>
<database.url>${database.url}</database.url>
<database.username>${database.username}</database.username>
<database.password>${database.password}</database.password>
</properties>
And tried reading with System.getProperty("database.username"), but it gave me null.
The reason for the ${database.url} and so on, is that it gets its values from either a default settings.xml or a user specific settings.xml, and that is how I need it to be. We are already using the sql-maven-plugin to bootstrap the database, but it only gets run once before all junit tests are run, and that is not what I need, I need it to run for every test to ensure a clean database.
I can easily make some code that drops my tables and so on, but I need the correct database properties from the correct settings.xml.
Bernd you talked about making a plugin that gets called before every test, how can I do this?

Sounds like this might help you:
- Create a Maven plugin which is executed in any phase >>bevore<< test,
e.g. 'generate-test-resources'. This will make it possible to set up the
database. This plugin might help for starting the database (only if you're
using HSQL):
http://gforge.openehealth.org/gf/project/development/wiki/?pagename=Documentation+HSQLDB+plugin
, but there are others, too.
- Reading of POM-properties inside a Maven plugin is easy and described
here:
http://www.sonatype.com/books/mvnref-book/reference/writing-plugins-sect-mojo-params.html#writing-plugins-sect-param-values
However, the scenario described by you clearly indicates that this is not
a unit test instead it is an integration test where other rules/plugins
might apply, e.g. maven-invoker-plugin. But this would recommend a
restructuring of your project and might not be what you want.

have you taken a look at the http://mojo.codehaus.org/sql-maven-plugin/
Maven-sql-plugin and/or to the
http://maven-plugins.sourceforge.net/maven-dbunit-plugin/
maven-dbunit-plugin not to forget http://www.dbunit.org/ dbUnit
itself...
Kind regards

Set them in the pom.xml via properties, eg.:
<project>
<properties>
<database.username>nobody</database.username>
</properties>
</project>
And access these properties in Java via
System.getProperty("databse.username").
