Question

我们现有的Web应用程序是使用 JDK 1.6 开发的，并使用maven（2.2.1）构建的。内置的构件（war / ear）使用Java 7部署到环境中。

自2018年6月起，旧产品 TLS 1.0＆1.1 协议将不再受Maven，JFrog等各种产品支持。任何访问maven或JFrog的客户端都需要使用TLS 1.2。我们正在使用Bamboo for CI，它当前使用JDK 1.6进行构建，并且由于旧式协议，当前所有构建都失败了。使用Java 1.8构建可以解决问题，但是我不确定如果我使用Java 1.8构建（行家）并将工件（war / ear）部署到使用Java 1.7的环境中是否会出现任何问题。任何指针都会有所帮助。

更新-1

我们决定将构建版本添加到Java 1.8，因为当我们尝试使用Java版本1.7.0_80进行构建（Maven）时，出现以下错误：

Java 1.8解决了构建失败的问题，但是我不确定如果将工件（war / ear）部署到使用Java 1.7的环境中会不会出现任何问题

更新-2 如khmarbaise所述，我在我的方案中使用了工具链，以下是详细信息：

MAVEN_JAVA_HOME和JAVA_HOME-JDK 1.8的路径

Maven版本-2.2.1

更新了我的应用程序父pom.xml，使其包含工具链插件，如下所示：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-toolchains-plugin</artifactId>
<version>1.1</version>
<executions>
  <execution>
    <goals>
      <goal>toolchain</goal>
    </goals>
  </execution>
</executions>
<configuration>
  <toolchains>
    <jdk>
      <version>1.6</version>
      <vendor>sun</vendor>
    </jdk>
  </toolchains>
</configuration>

toolchains.xml文件（如下所示）是用于在其中设置工具链安装路径的配置文件。我已将此文件放在/.m2目录中。

 <?xml version="1.0" encoding="UTF8"?>
<toolchains>
  <!-- JDK toolchains -->
  <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.6</version>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>C:\Program Files\Java\jdk1.6.0_45</jdkHome>
    </configuration>
  </toolchain>
</toolchains>

我已在本地验证构建成功。我需要验证如何将toolchain.xml文件传递给我的Bamboo配置。

有关如何配置工具链的详细信息，请参见https://maven.apache.org/guides/mini/guide-using-toolchains.html。

正如khmarbaise所提到的，我在我的场景中使用了工具链，以下是详细信息：
