当我尝试使用maven安装项目时出现此错误。 我读了很多帖子说这个错误是因为maven正在使用另一个版本的java但是这不是我的情况(我认为),因为我运行的每个命令都说使用的版本是java 1.7。
这是终端的结果:
Maven installation error:
Failure executing javac, but could not parse the error:
javac: invalid target release: 1.7
Usage: javac <options> <source files>
use -help for a list of possible options
mvn -version的输出
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 12:22:22-0300)

pom.xml(编译器插件部分):

<configuration>

<target>1.7</target>
</configuration>
</plugin>
一切看起来都不错,但一直都是错误。
答案 0 :(得分:2)
将maven-compiler-plugin
版本更新为 3.3 :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version> <!-- HERE -->
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
JAVA_HOME
如何设定?
Java home:/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/jre
您需要将此更正为/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/
Why I am not able to see the JAVA_HOME path on my MAC OS X 10.11?
