Maven编译“找不到符号" [英] Maven compile "Cannot find symbol"

问题描述

出于某种原因，这个命令在我的本地机器上运行良好:

For some reason this command works fine with my local machine:

mvn clean install -DskipTests=true -Psdk

但是对于 Codeship，它现在可以工作并抛出此找不到符号"错误.在 Codeship 中，完整的命令是:

However for Codeship it does now work and throws this "Cannot find symbol" error. In Codeship the full command is:

jdk_switcher use oraclejdk8
echo $JAVA_HOME
mvn clean install -DskipTests=true -Psdk

在 POM 中，存储库有:

In the POM the repository have this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
        <source>1.7</source>
        <target>1.7</target>
    </configuration>
</plugin>

错误:

[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ client-app ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 65 source files to /home/rof/src/bitbucket.org/company/client-app/target/classes

推荐答案

您的 Maven 正在读取 Java 版本为 1.8，而 pom.xml 表示版本为 1.7.

Your Maven is reading Java version as 1.8, Where as the pom.xml says the version is 1.7.

尝试安装所需的版本.

如果已经安装，请检查您的 $JAVA_HOME 环境变量，它应该包含 Java JDK 8 的路径.如果找不到，请修复您的环境变量.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 8. If you dont find it, fix your environment variable.

也删除线

 <fork>true</fork>
     <executable>${JAVA_1_8_HOME}/bin/javac</executable>

来自 pom.xml
