JDK : 1.7
Maven 컴파일러 플러그인 :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
</plugin>
위의 설치 대상 실행 오류가 발생하면 어떻게 해결할 수 있습니까?
답변
Java 7에서 작동하지 않는 maven war 플러그인 버전이 사용 중일 수 있습니다 . 에 따라 이 문제 (비슷한 문제를 설명하는), 2.1.1
메이븐 전쟁 플러그인의 버전은 작동합니다.
pom.xml에 다음을 포함하십시오.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
</plugin>
답변
나는 mvn install
. 나는 mvn clean
첫 번째를 수행하고 mvn install
.
maven 2.1.1, JDK 1.7.0.45 사용.
답변
확인되었습니다. Maven 2.x를 사용하는 JDK7에서이 오류가 발생합니다.
Maven 2.2.1 및 JDK7을 사용하고 있는데이 오류가 발생했습니다. JDK를 버전 1.6으로 변경했는데 제대로 작동합니다.
답변
JDK 버전 및 Maven 버전을 변경하는 대신 다음을 시도하십시오.
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
<version>2.3.2</version>
</plugin>
답변
확인, maven 3.0.2 및 jdk 1.7.0_02에서 동일한 문제가 발생했습니다. jdk 1.6.0_30에 대해 실행 한 후 잘 컴파일되었습니다.
답변
버전이 문제라고 생각하지 않습니다. 내 대상 폴더를 삭제하고 (webapp-cache.xml이 포함되어 있기 때문에) Maven 설치를 다시 수행했습니다.
답변
Apache Maven WAR Plugin 3.0.0은 모든 문제를 해결했습니다.
<artifactId>maven-war-plugin</artifactId>
<version>3.0.0</version>
jdk 1.6, 1.7 또는 1.8을 사용하는 것은 중요하지 않습니다.
