Gradle和Log4j - 嘗試構建時不支持Major.minor版本51.0

Question

我正在使用gradle來構建和分發項目，但每當我嘗試使用build命令時，我都會收到錯誤。

這是錯誤消息：

C:\Users\jamatic\workspace\PersonModule>gradle clean build cleaneclipse eclipse
--stacktrace
:clean
:compileJava
error: Exception thrown while constructing Processor object: org/apache/logging/
log4j/core/config/plugins/processor/PluginProcessor : Unsupported major.minor ve
rsion 51.0
:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':compile
Java'.

C:\Users\jamatic\workspace\PersonModule>

我檢查了我的build.gradle文件，我發現源兼容性是1.6。 這是我的Gradle構建文件：

/*** Gradle build file for PersonModule ***/

apply plugin: 'java'
apply plugin: 'java-library-distribution'
apply plugin: 'eclipse'

sourceCompatibility = 1.6

version = '2.2.5.5'

repositories {
    mavenCentral();

    ivy {
        url "Y://dev/shared-libs/ivy2"
    }
}

dependencies {
    compile 'no.solarsoft.admit.client:Venus2Core2:2.0+'
}

jar {
    // Keep jar clean:
    exclude 'META-INF/*.SF', 'META-INF/*.DSA', 'META-INF/*.RSA', 'META-INF/*.MF'

    manifest {
       attributes 'Main-Class': 'no.solarsoft.venus2.application.personmodule.PersonModule',
                  'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' ')
    }
}

我還檢查了java版本和java構建路徑：

我希望有人可以幫我找到這個錯誤的解決方案。 謝謝！

PS我認為這個問題在某種程度上與其他不受支持的major.minor問題有所不同。

Answer 1

看看PluginProcessor類，它會導致錯誤。 它是一個與Log4j2相關的類，因為庫2.4版本需要Java 7.看起來，你的一些依賴項或子項目依賴於Log4j2版本更大或等於2.4。
