Gradle testScoverage失败，NoClassDefFoundError使用MINA SSHD的项目.&l

Question

我有一组使用MINA SSHD (org.apache.sshd)的类。这些类具有在1.7.0版本的MINA上运行的测试。我现在迁移到2.8.0，并重新运行了测试。我从MINA获得两个特定类的NoClassDefFoundError:

22:40:46.606 [sshd-SshServer[55f94b13](port=8022)-nio2-thread-2] DEBUG org.apache.sshd.server.session.ServerSessionImpl - readIdentification(ServerSessionImpl[null@/127.0.0.1:56869]) client version string: SSH-2.0-APACHE-SSHD-2.8.0

和

22:59:22.798 [sshd-SshServer[55f94b13](port=8022)-nio2-thread-2] DEBUG org.apache.sshd.server.session.SessionFactory - messageReceived(Nio2Session[local=/127.0.0.1:8022, remote=/127.0.0.1:57245]) failed NoClassDefFoundError to handle message: Could not initialize class org.apache.sshd.common.SshConstants$LazyMessagesMapHolder
java.lang.NoClassDefFoundError: Could not initialize class org.apache.sshd.common.SshConstants$LazyMessagesMapHolder
at org.apache.sshd.common.SshConstants.getCommandMessageName(SshConstants.java:200)

奇怪的是，它说它找不到一个类是sshd-common工件的一部分，而其他类可以毫无问题地找到。

在我的主依赖项中，我使用2.8.0:

dependency group: 'org.apache.sshd', name: 'sshd-common', version: '2.8.0'
dependency group: 'org.apache.sshd', name: 'sshd-core', version: '2.8.0'
dependency group: 'org.apache.sshd', name: 'sshd-scp', version: '2.8.0'
dependency group: 'org.apache.sshd', name: 'sshd-sftp', version: '2.8.0'

在编写代码和测试的特定项目中，我也引入了特定的版本:

dependencies {
compile group: 'org.apache.sshd', name: 'sshd-common', version: '2.8.0'
compile group: 'org.apache.sshd', name: 'sshd-core', version: '2.8.0'
compile group: 'org.apache.sshd', name: 'sshd-scp', version: '2.8.0'
compile group: 'org.apache.sshd', name: 'sshd-sftp', version: '2.8.0'
compile project(':commands:expect4j')
compile project(':common:utils')
compile group: 'net.jcazevedo', name: 'moultingyaml_2.12'
compile group: 'org.scala-lang', name: 'scala-reflect', version: scalaVersion
compile group: 'org.bouncycastle', name: 'bcprov-jdk15on'
compile group: 'org.bouncycastle', name: 'bcpkix-jdk15on'
compile group: 'com.typesafe.scala-logging', name: 'scala-logging_2.12'
}
apply from: new File(rootProject.projectDir, 'gradle/scala.gradle')

没有其他关于org.apache.sshd的引用。我错过了什么?

Answer 1

Mina 2.8.0使用slf4j 1.7.32版本。

尝试添加此依赖版本。

implementation group: 'org.slf4j', name: 'slf4j-api', version: '1.7.32'
