Compiling pgjdbc 42.2.28.jre7

[imranzaheer612]

I am trying to compile pgjdbc for jre7. I am using the pgjdbc-jre7 repo but that repo only support up to the version 42.2.12. When I use same repo to compile for 42.2.28 I get compilation errors.

How can I compile pgjdbc 42.2.28.jre7?

42.2.28 is built from release/42.2.x branch: https://github.com/pgjdbc/pgjdbc/tree/release/42.2.x

.jre7 is a subproject: https://github.com/pgjdbc/pgjdbc/tree/release/42.2.x/pgjdbc-jre7

• I am using https://github.com/pgjdbc/pgjdbc-jre7 to compile release/42.2.x using maven.
• I am still getting compilation errors
• I guess these errors are from the notation @Nullable. I tried adding javax.annotation but still no progress. Am I doing some thing wrong because the same pgjdbc-jre7 repo works fine for REL42.2.12 but not for the latest 42.2.28

Please do not use pgjdbc-jre7 repository unless you want to rebuild releases <=42.2.12
The latest 42.2.x is 42.2.30, and its sources are storied in pgjdbc/pgjdbc repository.

Should I be using Java 7 for the compilation. Or using targeted Jre7 with jdk8. Because I am facing errors running gradlew on Java7.

Exception in thread "main" javax.net.ssl.SSLException: Received fatal alert: protocol_version

Please use Java 8. It will target 1.7 bytecode: https://github.com/pgjdbc/pgjdbc/blob/release/42.2.x/pgjdbc-jre7/build.gradle.kts#L58-L59
