Is isReleaseBuild() part of the Android Gradle DSL

问题:

I followed instructions similar to these:

Android Library Gradle release JAR

However, I get the following error:

Could not find method isReleaseBuild() for arguments [] on project ':myProject'.

None of the examples I saw on Maven integration define this function, so I assumed it was built-in. However, I get this error with Gradle 1.12 and 2.1, and Android plugin 0.12.+ and 0.13.+

If it's not a built-in function, what is the best practice for defining it?

回答1:

No. It is user defined, but seems to permeate examples because a lot of Gradle examples are copied.

This is the way I ended up defining it, so that I could pass in -PMAVEN_RELEASE_BUILD on the command line to turn on release builds.

def isReleaseBuild() {
    return hasProperty("MAVEN_RELEASE_BUILD") && MAVEN_RELEASE_BUILD == "true";
}

Some people also like to define as version names ending in -SNAPSHOT. I do not prefer to do this, because I want to be able to choose whether to build a release or debug build without checking in a change to gradle.properties.

def isReleaseBuild() {
    return !VERSION_NAME.contains("SNAPSHOT");
}
