Re: [java code coverage] Does Jacoco 0.8.7 JAR supports JDK 21 classes

No, this will not work. JaCoCo 0.8.7 does not support Java 21 class files. Also not for report generation.

I have a JacocoAgent running in server model with Jacoco 0.8.12 JAR in a Testenvironment. The exec created in the Testenv I am downloading through a Java service and trying to generate reports from 0.8.7 Jacoco Jar and JDK 21 classes. Will this setup work and if not where is the issue since exec format has not changed from 0.8.7 to 0.8.12, right?

Hello,
I am little bit confused. Class files are supported back till 1 but for older jacoco versions right? Does it mean 0.8.11 and above will support creating reports from java 21 classes?

Dear Mehul,


Here you find for 0.8.7:

  • JaCoCo now officially supports Java 15 and 16 (GitHub #1094, #1097, #1176).
  • Experimental support for Java 17 class files (GitHub #1132).

JaCoCo 0.8.7 was released in 2021, Java 21 was released 2 years later…

The minimum required Java runtime version for all JaCoCo releases is Java 5. Class files are supported back to Java 1.0.

Regards,

Does Jacoco 0.8.7 JAR supports JDK 21 classes. Do we have a table where you guys maintain backward comparibility of JARs and JDk version.
