[英]Is it possible to specify in a POM a specific JDK to run a given maven-plugin?
I have been asked to provide for signing a jar using specific JDK 1.8 whereas project is being 1.7 compliant. 我被要求提供使用特定的JDK 1.8签名jar的协议,而该项目是1.7兼容的。 How can I achieve this, assuming it is feasable? 假设可行,我如何实现呢? I have a default JDK 1.8 with which a jenkins job would execute a maven job 我有一个默认的JDK 1.8,詹金斯作业将使用它执行Maven作业
The application is 1.7 coded so in its pom.xml there is the following configuration: 该应用程序是1.7编码的,因此在其pom.xml中具有以下配置:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>.....</version>
<configuration>
.....
<source>1.7</source>
<target>1.7</target>
.....
</configuration>
</plugin>
As they need to sign the jar, and they have been recommended to use jarsigner of 1.8 , I wonder how can I force maven-jarsigner-plugin .... 因为他们需要签名jar,并且建议他们使用1.8的jarsigner ,所以我想知道如何强制maven-jarsigner-plugin...。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jarsigner-plugin</artifactId>
<version>...</version>
<executions>
<execution>
<id>sign</id>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
<configuration>
<keystore>${keystore.file}</keystore>
<alias>${keystore.alias}</alias>
<storepass>${keystore.password}</storepass>
<storetype>${keystore.type}</storetype>
<sigfile>XXX</sigfile>
</configuration>
</plugin>
... to use JDK8 Is that feasable? ... 使用JDK8可行吗? How? 怎么样?
many thanks 非常感谢

Just configure only JDK8 for this. 只需为此配置JDK8。
The maven-compiler-plugin
will assure you to compile Java 1.7 compliant code. maven-compiler-plugin
将确保您编译Java 1.7兼容代码。
On the other hand the maven-jarsigner-plugin
will transparentely sign the jars using the JDK8. 另一方面, maven-jarsigner-plugin
将使用JDK8透明地签名罐子。
Just to be clear jarsigner
is a JDK utility, it's impossible to run jarsigner
of JDK 1.8 in a older (say 1.7) version way. 为了清楚jarsigner
是一个JDK实用程序,不可能以较旧的版本(例如1.7)运行JDK 1.8的jarsigner
。
