Re: [platform-releng-dev] 4.17 I-Build: I20200611-1800 - BUILD FAILED
Sorry for resurfacing this old thread.  I did try to compile my simple project [1] against Java 7 SDK and it works for me.  It also works if I configure the maven build of my project to use ECJ.  I'm not sure why it fails in our Eclipse builds with tycho but not with a simple maven project that targets to Java 7 and is compiled against a Java 7 libraries.
 
Note that if I try to compile against one of the new methods in FrameworkUtil that returns an Optional it then fails as expected.  But compiling against old methods with no Optional in their signature compile fine when also compiling against the Java 7 SDK libraries.
 
This only concerns me because it would appear Tycho will aggressively force all bundles that use the existing FrameworkUtil.getBundle(Object) method to move up to Java 8 in order to compile.  Some will see this as a good thing, nobody should be targeting Java 7 at all anymore!  But others will see this as an unnecessary change they have to make just to work around some build issue.
 
In the end this is not really an Eclipse Project issue, we can easily move all our bundles to Java 8 or later.  I only worry about consumers of the new release that may run into this when they start compiling against our next release.

Tom,

my guess is that you don't/didn't have a JRE 1.7 installed and hence a newer JRE is/was bound to the specified EE. There's a warning for that case on the project.

Why would everything have to move up in their execution environment just because the internals of FrameworkUtil reference Optional?  Is this using ECJ or javac to compile.  I'm fairly certain javac would not flag this as an error.

Our build system build against the JVM version as specified in BREE. Thus when the bundle has BREE 1.7 it fails to compile as its dependent bundle uses Optional and it's not found.

Please go to https://ci-staging.eclipse.org/releng/job/I-build-4.17/21/consoleand check the build failure.


Error is:

This makes me think it's related to https://git.eclipse.org/c/equinox/rt.equinox.framework.git/commit/?id=ce9a3f27b26b7bbde23b747a0aa7ad0c470b55d2 . I'm looking further into it.
