是什么原因导致“发生未知的编译问题”？

标签： java maven compiler-errors

尝试使用Maven编译项目时，出现以下错误：C#。

我尝试运行以下命令以获取有关该错误的更多详细信息，但仍然无法弄清楚：SQL Server

这是我得到的日志：

要注意，在我将项目中的Java版本从1.8迁移到11之后，这种编译问题就开始发生。

3 个答案:

答案 0 :(得分：0)

下面给出了以下步骤，

1) Run as Maven clean
2) Go to Project(top bar in eclipse) and clean it
3) Run as Maven install

（有时需要在Eclipse中清洗两次，然后再运行mvn install） 希望这会有所帮助。

答案 1 :(得分：0)

您正在使用旧版本的maven插件（3.1）来编译代码。要使用maven编译Java 11代码，请使用具有以下配置的maven插件：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>11</release>
    </configuration>
</plugin>

答案 2 :(得分：0)

我遇到了同样的问题。删除后我能够摆脱这个问题

-Werror

来自 pom.xml 文件中 maven 编译器插件配置的行。

maven-compiler-plugin 删除前配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <source>1.8</source>
        <target>1.8</target>
        <compilerArgument>-Werror</compilerArgument>
    </configuration>
</plugin>

maven-compiler-plugin 删除上面一行后的配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.3</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <source>1.8</source>
        <target>1.8</target>
    </configuration>
</plugin>
