What is the difference between allprojects and subprojects

Question

On a multi-project gradle build, can someone tell me what exactly is the difference between the \"allprojects\" section and the \"subprojects\" one? Just the parent directo

Answer 1

In a multi-project gradle build, you have a rootProject and the subprojects. The combination of both is allprojects. The rootProject is where the build is starting from. A common pattern is a rootProject has no code and the subprojects are java projects. In which case, you apply the java plugin to only the subprojects:

subprojects {
    apply plugin: 'java'
} 

This would be equivalent to a maven aggregate pom project that just builds the sub-modules.

Concerning the two syntaxes, they do the exact same thing. The first one just looks better.
