Release Notes

gretty-gradle-plugin/gretty

v4.0.3

• Replace internal Gradle API usage with public API #​263
  Thank you, @​octylFractal, for making Gretty better.
• Upgraded default versions of Tomcat to 10.0.22, and Jetty to 11.0.11

v4.0.2

• Use Tomcat 10.0.21
• Use Jetty 11.0.9
• Use Gradle 7.4.2 for testing Gretty
• Added exclusion patterns for commons-cli and commons-io classes to FilteringClassLoader #​258
  Adding the patterns fixes a bug which gave preference to the commons-cli and commons-io versions
  that Gretty uses, rather than using the JARs bundled with the webapp (which is the correct behavior).
• Upgrade to Logback 1.3.0-alpha14
• Remove Groovy-based logging configuration in response to Log4Shell #​249

v4.0.1

• Fix inability to build a product due to missing Groovy dependencies (#​238).

• Version upgrades to mitigate some CVEs (#​252). Thanks to @​dutta1kartik3.

v4.0.0

• Gretty requires JDK11+.

• Gretty supports only Tomcat 10 and Jetty 11 (Jakarta versions of the containers). All thanks goes to @​f4lco.

v3.0.9

• Replace internal Gradle API usage with public API #​265
  Thank you, @​octylFractal, for making Gretty better.

v3.0.8

Thanks @​boris-petrov for patch #​258, that updated exclusion patterns for FilteringClassLoader, which causes Gretty to correctly use the commons-io and commons-cli JARs from the webapp classpath rather than defaulting on the versions shipped with Gretty.

v3.0.7

• Fix inability to build a product due to missing Groovy dependencies (#​238)

v3.0.6

• JDK 16 support
