使用maven / ivy存储库获取java rt.jar

Question

JDKs get installed in different places on different machines, I want to be able to support building with Java 7 targeting a Java 6 runtime.

I can specify -source 1.6 -target 1.6 to tell javac to target that runtime environment. I can specify a -Xbootclasspath to tell it use a specific runtime jar

However Java 7 doesn't install java 6 runtime jars (not surprisingly).

When I look in the maven repository it just seems to have just up to 1.5: http://mvnrepository.com/artifact/com.sun/rt

Has the group id changed in 1.6? Is it available via a maven / ivy dependency?

Answer 1

You can manually add artifacts to a local maven repository (fe nexus or artifactory) and declare a dependency on that in your pom.

On the other hand: If you have a jdk installed you have already all classes in place to build for lower level runtimes, so there should be no need for the approach you described.
