Hi all, registry.xboot module has 3 java interfaces (SQLXML, RowId and NClob) they were empty and has the comment: Dummy implementation for jdk6. I removed that module and went ahead.
However I'm facing issues getting the maven-scr-plugin to generate the "scr-plugin-generated" folder which contains the serviceComponents.xml etc. Following error occurs if I use the existing scr plugin version with java 10. [ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.7.4:scr (generate-scr-scrdescriptor) on project carbon-kernel: Execution generate-scr-scrdescriptor of goal org.apache.felix:maven-scr-plugin:1.7.4:scr failed: org.apache.felix.scrplugin.tags.annotation.AnnotationTagProvider is not an ImageIO SPI class When I upgrade the maven scr plugin version to 1.26.0 (latest) it complains that "No annotation processors found in classpath" So I added org.apache.felix.scr.annotations as an dependency according to instructions in Apache Felix documentation. Now i am getting the following error because scr-plugin-generated folder structure is still not generated. [ERROR] Manifest org.wso2.carbon:org.wso2.carbon.registry.core:bundle:4.4.34-SNAPSHOT : Input file does not exist: target/scr-plugin-generated/OSGI-INF/serviceComponents.xml I have tried this with multiple scr plugin versions and with and without upgrading the equinox version. No information is available on this issue in the community. Nobody seems to be using java 10 for OSGI stuff. I have asked about this issue on stackoverflow and apache felix users' mailing list. I am posting this in this thread as an update. Any help is appreciated.
