java

The java commandlet allows to install and setup Java. Also it supports devon4j. The arguments (devon java «args») are explained by the following table:

Table 1. Usage of devon java

Argument(s)	Meaning
setup	setup OpenJDK (install or update and verify), configurable via JAVA_VERSION (e.g. 8u222b10 or 11.0.4_11)
create «args»	create a new Java project based on devon4j application template. If a single argument is provided, this is the package name and is automatically split into groupId and artifactId. Use -DdbType=«db» to choose the database (hana, oracle, mssql, postgresql, mariadb, mysql, h2, hsqldb). Any option starting with dash is passed as is."
migrate [from «version»] [single]	migrate a devon4j project to the latest version. If for some reasons the current devonfw version (e.g. oasp4j:2.6.0) can not be auto-detected you may provide it manually after the 'from' argument. Also the 'single' option allows to migrate only to the next available version."
