Question

鉴于支持java 8的Bluemix announcement。我需要做什么才能在IBM Bluesmix构建管道（jazzhub构建和部署）中编译我的Java 8应用程序。

我已经设置了java8环境变量并使用以下内容重新启动了应用程序：

cf set-env <myApp> JBP_CONFIG_IBMJDK "version: 1.8.+"
cf restage <myApp>

我使用的特定“构建器类型”是“Maven”，我收到的失败是围绕java8中的新日期和时间类。

[ERROR] <...>/services/TestHelperService.java:[3,17] package java.time does not exist
[ERROR] <...>/services/TestHelperService.java:[37,17] cannot find symbol
[ERROR] symbol:   class LocalDateTime
[ERROR] location: class <...>.services.TestHelperService

Answer 1

要使用Java 8，您需要在build shell命令中更改JAVA_HOME环境变量：

export JAVA_HOME=~/java8

例如：

#!/bin/bash
#export JAVA_HOME=~/java8 - Bluemix have changed the java8 location
export JAVA_HOME=/opt/IBM/java8
mvn -B package

Answer 2

我还想在Bluemix Jazz构建管道中使用Java8。只是改变$JAVA_HOME对我不起作用。我还必须更新$PATH。

export JAVA_HOME=/opt/IBM/java8
export PATH=$JAVA_HOME/bin:$PATH

之后，maven在java8上运行。

Answer 3

嗨，这个解决方案对我来说不起作用，这是我的构建脚本

#!/bin/bash
echo "Java Home before $JAVA_HOME"
export JAVA_HOME=~/java8
echo "Java Home after $JAVA_HOME"
#mvn -B package -DskipTests
#mvn -B package

这是控制台输出，你可以看到在“export”命令后没有修改JAVA_HOME。

我可以确认在构建脚本中将JAVA_HOME设置为/ opt / IBM / java8确实有效（在2016-05-04上试用）：

#!/bin/bash
 echo "Java home before: $JAVA_HOME"
 export JAVA_HOME=/opt/IBM/java8
 echo "Java home after: $JAVA_HOME"
 mvn -B package

这导致输出：

Java home before: /opt/IBM/java
Java home after: /opt/IBM/java8

如前所述，部署阶段必须将JBP_CONFIG_IBMJDK设置为＆＃34;版本：1.8。+＆＃34; （cf set-env myApp JBP_CONFIG_IBMJDK "version: 1.8.+"或env中的行：manifest.yml的部分）或者（我做的是）你需要在manifest.yml中定义buildpack: java_buildpack。自2015年5月起，java_buildpack使用JDK8。

最后要注意的是在pom.xml中更改maven-compiler-plugin的源版本 - 当然 - 但这不是特定于Bluemix的。

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>(whatever version is current)</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

Bluemix devops构建管道支持java 8应用程序吗？
