Guillaume Nodet updated MTOOLCHAINS-49: --------------------------------------- Fix Version/s: 3.2.0 > Automatic discovery of JDK toolchains > ------------------------------------- > > Key: MTOOLCHAINS-49 > URL: https://issues.apache.org/jira/browse/MTOOLCHAINS-49 > Project: Maven Toolchains Plugin > Issue Type: Improvement > Reporter: Guillaume Nodet > Assignee: Guillaume Nodet > Priority: Major > Fix For: 3.2.0 > > > Add mojos to: > * display a human readable list of discovered JDK toolchains > * generate the toolchains.xml file for discovered JDK toolchains > * select a JDK toolchain with specific behaviour if the current JDK fulfils > the requirements > The generation of the {{toolchains.xml}} file is not necessary to use > discovered toolchains. The {{select-jdk-toolchain}} will select a toolchain > amongst explicitely configured toolchains and discovered toolchains. The > information for discovered toolchains are cached in > {{~/.m2/discovered-toolchains-cache.xml}} file by default. > The {{select-jdk-toolchain}} config below allows using the current JDK, or > any other discovered JDK >= 17. The benefit is that the current JDK can be > kept for speed, but ensuring the usage of any JDK 17 or higher if the current > jdk is below the requirements. > {code} > <profile> > <id>toolchains</id> > <build> > <plugins> > <plugin> > <groupId>org.apache.maven.plugins</groupId> > <artifactId>maven-toolchains-plugin</artifactId> > <version>3.1.1-SNAPSHOT</version> > <executions> > <execution> > <goals> > <goal>select-jdk-toolchain</goal> > </goals> > <configuration> > <version>[17,)</version> > </configuration> > </execution> > </executions> > </plugin> > </plugins> > </build> > </profile> > {code} > The {{display-discovered-jdk-toolchains}} shows human readable discovered > JDKs: > {code} > > mvn > > org.apache.maven.plugins:maven-toolchains-plugin:3.1.1-SNAPSHOT:display-discovered-jdk-toolchains > ... > [INFO] Discovered 13 JDK toolchains: > [INFO] - /Users/gnodet/.sdkman/candidates/java/21.ea.22-open > [INFO] provides: > [INFO] vendor: Oracle Corporation > [INFO] runtime.version: 21-ea+22-1890 > [INFO] runtime.name: OpenJDK Runtime Environment > [INFO] version: 21-ea > ... > {code} > while the {{generate-jdk-toolchains-xml}} will write the output in xml format: > {code} > > mvn > > org.apache.maven.plugins:maven-toolchains-plugin:3.1.1-SNAPSHOT:generate-jdk-toolchains-xml > > > ... > <?xml version="1.0" encoding="UTF-8"?> > <toolchains xsi:schemaLocation="http://maven.apache.org/TOOLCHAINS/1.1.0 > http://maven.apache.org/xsd/toolchains-1.1.0.xsd" > xmlns="http://maven.apache.org/TOOLCHAINS/1.1.0" > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> > <toolchain> > <type>jdk</type> > <provides> > <vendor>Oracle Corporation</vendor> > <runtime.version>21-ea+22-1890</runtime.version> > ... > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
