[Performance] - Import New Project

[mamilic]

When I import large projects, let's take into example spring-boot, I can see in bottom bar the Java notification, and to me it seems like dependecies are downloaded one by one. I am wondering whether that is the case, and could it be somehow parallelized?

You may want to take a look at https://docs.gradle.org/current/userguide/performance.html

Thank you @snjeza , will this improve the downloading of dependencies if there is only one module? If I understood correctly this will only allow parallel build if there are multiple modules?

You can also review gradle/gradle#28893

Thank you a lot! I just noticed, what will happen in case whe I want the sources to be downloaded, does that happens within jdtls or within respective dependency resolution handler(maven, gradle)?

For Maven, it's handled by JDT-LS, and the classpath is updated accordingly See https://github.com/eclipse-jdtls/eclipse.jdt.ls/blob/master/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/managers/MavenSourceDownloader.java ). For Gradle, I think that's handles by the Gradle support, which is packaged in JDT-LS. As long as the maven repository, or the gradle repository has published the source artifacts, then it should work.
