J'ai essayé de déployer l'application la plus simple des guides spring.io Guide
Mais j'ai quelques problèmes. Ce que j'ai fait:
remote: [INFO] BUILD FAILURE remote: [INFO] ------------------------------------------------------------------------ remote: [INFO] Total time: 12.608 s remote: [INFO] Finished at: 2020-01-23T18:20:18Z remote: [INFO] ------------------------------------------------------------------------ remote: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project milliapp: Fatal error compiling: invalid target release: 11 -> [Help 1] remote: [ERROR] remote: [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. remote: [ERROR] Re-run Maven using the -X switch to enable full debug logging. remote: [ERROR] remote: [ERROR] For more information about the errors and possible solutions, please read the following articles: remote: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException remote: remote: !

Résolu. Supprimé cette partie du code
<properties> <java.version>11</java.version>
Deuxième solution:
maven-compiler-plugin 3.8.1
avec cette configuration:<plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.1</version> <configuration> <source>8</source> <target>8</target> <testSource>8</testSource> <testTarget>8</testTarget> <showDeprecation>true</showDeprecation> <compilerArgument>-Xlint:unchecked</compilerArgument> </configuration> </plugin> </plugins>
Dans le fichier pom.xml, commentez sous la ligne dans la balise properties.
<java.version>11</java.version>
Cela a fonctionné pour moi.
