问题：

如何在Apache Storm 0.9.3的maven中启用java 7

澹台奇略

2023-03-14

我目前正在Ubuntu 14.04 LTS中使用Apache Storm 0.9.3。我遇到Apache Storm 0.9.3中的maven编译器继续使用Java 6，尽管我已经安装了Java 7。

我的Ubuntu中的Java版本：

java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) Client VM (build 24.80-b11, mixed mode)

我的Ubuntu中的Maven版本：

Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.7.0_80, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-oracle/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-52-generic", arch: "i386", family: "unix"

以下是我遇到的错误：

首先，您必须安装Java 7。

如中所示

[警告]'报告。插件。插件。组织的“版本”。阿帕奇。专家插件：缺少maven javadoc插件。@组织。阿帕奇。Storm：Storm：0.9.3，/home/user/。m2/repository/org/apache/storm/storm/0.9.3/storm-0.9.3。pom，第694行，第21列[警告]'报告。插件。插件。组织的“版本”。阿帕奇。专家插件：缺少maven surefire报告插件。@组织。阿帕奇。Storm：Storm：0.9.3，/home/user/。m2/repository/org/apache/storm/storm/0.9.3/storm-0.9.3。pom，第660行，第21列

转到您的主目录并将cd光盘刻录到/。m2/repository/org/apache/storm/storm/0.9.3/然后是nano或vi storm-0.9.3。pom。

搜索

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
        </configuration>
    </plugin>

如果您打算使用java-7-oracle，请将1.6修改为1.7。如果您使用的是nan，您可以使用Ctrl W轻松搜索
