update: found out google wants move use cloud tools appengine maven plugin: https://cloud.google.com/appengine/docs/standard/java/tools/migrate-maven
if use recommended setting , run gcloud appengine:deploy exact same error got in intellij before. using old appengine maven plugin works goes against google recommends.
it seems need manage correctly versions in pom.xml. plugins not accessible more under specified version.
i've tried:
<plugins> ... <plugin> <groupid>com.google.appengine</groupid> <artifactid>appengine-maven-plugin</artifactid> <!--<version>${appengine.target.version}</version>--> <version>1.8.3</version> <configuration> </configuration> </plugin> <plugin> <groupid>org.eclipse.jetty</groupid> <artifactid>jetty-maven-plugin</artifactid> <!--<version>${jetty.maven.plugin}</version>--> <version>9.4.0.v20161208</version> </plugin> </plugins> and i've started server without problem.
plugin , dependency version can different (because of shifted releases or cleaning repositories). can use plugin versions i've specified or play changing ones more if want use same version dependency , plugin.
