How to read a properties files and use the values in project Gradle script?
<p>I am working on a Gradle script where I need to read the <code>local.properties</code> file and use the values in the properties file in <code>build.gradle</code>. I am doing it in the below manner. I ran the below script and it is now throwing an error, but it is also not doing anything like creating, deleting, and copying the file. I tried to print the value of the variable and it is showing the correct value.</p>
<p>Can someone let me know if this is the correct way to do this? I think the other way is to define everything in the <code>gradle.properties</code> and use it in the <code>build.gradle</code>. Can someone let me know how could I access the properties in <code>build.gradle</code> from <code>build.properties</code>?</p>
<p><code>build.gradle</code> file:</p>
<pre><code>apply plugin: 'java'

// Set the group for publishing
group = 'com.true.test'

/**
 * Initializing GAVC settings
 */
def buildProperties = new Properties()
file(&quot;version.properties&quot;).withInputStream {
        stream -&gt; buildProperties.load(stream)
}
// If jenkins build, add the jenkins build version to the version. Else add snapshot version to the version.
def env = System.getenv()
if (env[&quot;BUILD_NUMBER&quot;]) buildProperties.test+= &quot;.${env[&quot;BUILD_NUMBER&quot;]}&quot;
version = buildProperties.test
println &quot;${version}&quot;

// Name is set in the settings.gradle file
group = &quot;com.true.test&quot;
version = buildProperties.test
println &quot;Building ${project.group}:${project.name}:${project.version}&quot;

Properties properties = new Properties()
properties.load(project.file('build.properties').newDataInputStream())
def folderDir = properties.getProperty('build.dir')
def configDir = properties.getProperty('config.dir')
def baseDir  = properties.getProperty('base.dir')
def logDir  = properties.getProperty('log.dir')
def deployDir  = properties.getProperty('deploy.dir')
def testsDir  = properties.getProperty('tests.dir')
def packageDir  = properties.getProperty('package.dir')
def wrapperDir  = properties.getProperty('wrapper.dir')
