java - Maven compile "Cannot find symbol"

Question

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

mvn clean install -DskipTests=true -Psdk

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

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>

Error:

[INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ client-app ---

您的 Maven 将 Java 版本读取为 1.8，而 pom.xml 说版本是 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。

也删除线

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

从 pom.xml

我遇到过同样的问题。原因是其中一个类被用于

src/main/java/

实际上它存在于

src/test/java

如果您已正确导入依赖项，则可以尝试以下过程。
首先尝试-
mvn clean
如果成功运行，然后尝试-
mvn install
如果效果很好，那么您可以尝试
mvn compile
-这个过程对我有用。

我遇到了类似的问题，但是当我在 POM 中更改 Testng 版本时，它解决了这个问题。

<artifactId>testng</artifactId>
<version>6.9.8</version>       // Changed the version to 6.9.8
<scope>test</scope>
