Scala 为什么播放2.3.4和jacoco4sbt>；2.1.4是否因无此错误而失败？

我试图在Play 2.3.4（scala 2.10.4）应用程序中使用jacoco4sbt，但似乎只有2.1.4起作用。当我使用.5或.6时，会出现以下错误：

[error] (main/jacoco:fullClasspath) java.lang.NoSuchMethodError:
org.objectweb.asm.MethodVisitor.visitMethodInsn(ILjava/lang/String;Ljava/lang/String;Ljava/lang/String;Z)V

我试图向依赖项添加

asmall

（版本4.1和5.0.3），但这根本没有帮助

那么问题出在哪里呢？我需要添加任何额外的依赖项吗？

到5.0.1，即使这样，我也无法重现您的问题

项目/构建.属性

sbt.version=0.13.7-M3

项目/插件.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.4")

addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")

name := """play-jacoco"""

version := "1.0-SNAPSHOT"

enablePlugins(PlayScala)

scalaVersion := "2.11.2"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws
)

pipelineStages := Seq(rjs, digest, gzip)

jacoco.settings

插件/jacoco4sbt.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.4")

addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")

name := """play-jacoco"""

version := "1.0-SNAPSHOT"

enablePlugins(PlayScala)

scalaVersion := "2.11.2"

libraryDependencies ++= Seq(
  jdbc,
  anorm,

)

pipelineStages := Seq(rjs, digest, gzip)

jacoco.settings

构建.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.3.4")

addSbtPlugin("de.johoop" % "jacoco4sbt" % "2.1.6")

name := """play-jacoco"""

version := "1.0-SNAPSHOT"

enablePlugins(PlayScala)

scalaVersion := "2.11.2"

libraryDependencies ++= Seq(
  jdbc,
  anorm,
  cache,
  ws
)

pipelineStages := Seq(rjs, digest, gzip)

jacoco.settings

当我运行

jacoco:cover

时，它运行得很好

我们的不同点在哪里？

在查看Jacek answer并开始从我的项目中删除内容后，我发现这是由一些我不知道的运行引起的，这可能取决于不同的asm版本

为了解决这个问题，我刚刚更改了

project/plugins.sbt

中的依赖项以排除asm依赖项：

libraryDependencies ++= Seq(
  // (...)
  "net.sourceforge.pmd" % "pmd" % "5.1.3" exclude("org.ow2.asm", "asm")
)

---

Jacoco和PMD都重新开始工作。

请您再问一个问题（这样我们就不会劫持这个问题），添加解决方案，并将PMD作为答案，然后批准。“那太干净了！”杰克拉斯科夫斯基谢谢你的帮助。我将更新信息添加到了。谢谢！很好的合作。我喜欢。
