maven toolchains 简单说明

标签：Java jdk zulu maven 构建 简单 toolchains

很多时候我们项目可以会包含需要不同jdk 构建，比如有些只能使用jdk8，有些需要使用jdk11，toolchains 可以帮助我们解决此问题

一般玩法

创建一个toolchains.xml 目录，放到home 目录下，里边配置实际需要的jdk 版本（我们的环境可以安装多jdk）
项目构建的时候（使用的插件）使用配置的工具

• 参考配置

 

<?xml version="1.0" encoding="UTF-8"?>

<toolchains>

  <toolchain>

    <type>jdk</type>

    <provides>

      <version>1.8</version>

      <vendor>zulu</vendor>

    </provides>

    <configuration>

      <jdkHome>...../8.0.382-zulu</jdkHome>

    </configuration>

  </toolchain>

  <toolchain>

    <type>jdk</type>

    <provides>

      <version>11</version>

      <vendor>zulu</vendor>

    </provides>

    <configuration>

      <jdkHome>...../11.0.20-zulu</jdkHome>

    </configuration>

  </toolchain>

</toolchains>

• 项目使用

<plugin>

  <artifactId>maven-surefire-plugin</artifactId>

  <configuration>

    <!-- Need to run with Java 8, because `GuavaPatcher` runs too late, and

     `com.google.common.base.Stopwatch` has already been loaded. GuavaPatcher

      tries to re-define the Stopwatch class in the same classloader, but Java

      Java 11 no longer allows this. The existing workaround with that

      `GuavaPatcherRunner` runs into the same issue. A proper solution would be

      to implement a Java agent, which _is_ allowed to re-define classes.

      -->

    <jdkToolchain>

      <version>1.8</version>

    </jdkToolchain>

  </configuration>

</plugin>

说明

比如dremio 目前构建就需要配置toolchains，依赖的一些包构建只能使用jdk8
