+# This workflow will build a Java project with Maven and publish artifact to Maven Central (https://search.maven.org)

+# After deploy to https://s01.oss.sonatype.org finished, manual steps is required :
+# - Go to: https://s01.oss.sonatype.org/#stagingRepositories
+# - Check upload and if all is right, "Close" corresponding Staging Repository
+# - "Release" corresponding Staging Repository
+# - Wait some hours and then check availability of release on Maven central: https://search.maven.org/search?q=g:io.ecocode
