From the homepage for the plugin you're using, https://gwt-maven-plugin.github.io/gwt-maven-plugin/, last updated in 2017 with GWT 2.8.2:> NOTICE There is a new plugin (archetypes and eclipse integration), a fresh start that correctly support multi-module projects, it is not version-bounded with GWT, support multiples GWT versions and other fixes, improvements and best practices. This plugin is now considered the legacy GWT maven plugin (aka mojo GWT maven plugin) and the new one is considered the new generation GWT maven plugin (aka tbroyer GWT maven plugin). The legacy maven plugin is still supported but it is strongly encouraged to use the new one for new projects.GWT 2.12 can work with the old gwt-maven-plugin - be sure to specify <dependencies> _inside_ the plugin tag, and reference gwt-user and gwt-dev there. Otherwise, the plugin will continue to use the version of GWT it was built with. The "new" maven plugin does not have this limitation.May I ask how you were building with GWT 2.11 with the 2.10 plugin? If you weren't doing this, you potentially weren't using the full GWT 2.10 classpath after all...--On Friday, November 8, 2024 at 9:24:32 AM UTC-6 ora...@gmail.com wrote:The UnifyAst stack trace was from running Maven. I use gwt-maven-plugin version 2.10? Could it be the reason for the classpath issue? There is no newer version. And I know that there exists a new maven plugin to run the GWT compiler. I am digging through the maven log trying to figure out what is wrong with the classpath but perhaps GWT 2.12 cannot work with gwt-maven-plugin 2.10. Can it?Thanks,OlegOn Fri, Nov 8, 2024 at 9:22 AM Colin Alworth <co...@colinalworth.com> wrote:I'm afraid I can't tell a lot from that, except that the line numbers of UnifyAst don't match up with GWT 2.12 - they do however line up with 2.11 (though I didn't test any other versions), so you may additionally have a classpath issue of some kind. That could potentially cause this NoSuchMethodError.--On Friday, November 8, 2024 at 8:06:27 AM UTC-6 ora...@gmail.com wrote:Thank you Colin.The compiler gives a different issue though. I have updated to the latest guava but it does not help.

We have a fix for that merged, you can test the HEAD-SNAPSHOT release from the sonatype snapshots repository (https://oss.sonatype.org/content/repositories/snapshots/), or wait for the 2.12.1 release (see https://github.com/gwtproject/gwt/milestone/24, will likely only contain that fix plus one other long-standing issue that impacts latest jsinterop-base and elemental2).You can also find the failing code (easier to spot running the compiler) and add the missing "{}"s in the "if" that contains the switch statement, that will work around this bug.On Friday, November 8, 2024 at 6:53:40 AM UTC-6 ora...@gmail.com wrote:Hello,I have updated from GWT 2.11 to 2.12.
