Accessing a Properties File From a Different Project

Question

I am developing a custom maven plugin. When I read my properties file of custom plugin everything is well however when I run it at different project as a plugin how can I get that projects properties file, it always looks at resources directory of itself as usual because of:

I have that:

Properties allProperties = new Properties();
allProperties.load(this.getClass().getResourceAsStream("/tokens.properties"));

and I tried that:

Properties allProperties = new Properties();
ClassLoader loader = Thread.currentThread().getContextClassLoader();
allProperties.load(loader.getResourceAsStream("/tokens.properties"));

but didn't work. Any ideas?

PS: When I run it it reads from plugins properties file. My properties files are under

src/main/resources

I use that at my poms:

<build>
     ...
    <resources>
        <resource>
            <directory>src/main/resources/</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
     ...
</build>

and my properties file:

project.version = ${project.version}

Answer 1

Properties allProperties = new Properties();
ClassLoader loader = Thread.currentThread().getContextClassLoader();
allProperties.load(loader.getResourceAsStream("/tokens.properties"));

You were close. That's indeed the right class loader, but the wrong path. Remove the leading slash.

allProperties.load(loader.getResourceAsStream("tokens.properties"));
