本文主要介绍Java中,使用Maven编译简单的Java 10/Java 11项目,运行mvn -X install -DskipTests=true报错异常的解决方法 。

pom.xml文件内容如下:

<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>example</name>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <release>10</release>
            </configuration>
        </plugin>
    </plugins>
</build>

异常信息如下

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile (default-testCompile) on project example: Execution default-testCompile of goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:testCompile failed.

解决方法

1)第一种解决方法

从2018年7月30日起,要解决上述问题,可以将maven中使用的java版本配置为JDK/11以下的任意版本,并使用maven-compiler-plugin:3.8.0指定9、10和11的版本,而不需要任何显式依赖关系。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>11</release>  <!--or <release>10</release>-->
    </configuration>
</plugin>

2)第二种解决方法

maven-compiler-plugin依赖于ASM的旧版本,它还不支持Java 10(和Java 11)。但是,可以显式指定ASM的正确版本:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.7.0</version>
<configuration>
<release>10</release>
</configuration>
<dependencies>
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>6.2</version> <!-- Use newer version of ASM -->
</dependency>
</dependencies>
</plugin>
